Electricity - Class 10th Science 🔥| One Shot | Prashant Kirad

0:03 So burning is called fire and roasted is called raga and that which makes science easy Prashant Kirad says so hi everyone I am I am yours Prashant Bhaiya, soon Tell me how are you everyone how is your energy how is the josh meter and and and and and and you How are you all? He will tell me once, right? please tell me quickly in chat how are you How are you all? I will tell you all soon. what happened brother what happened ok no all good yes we have reached live reach brother am I live or not hey I can't go live what what It's done, am I just talking like that Who am I talking to I'm live

0:49 I am there, yes I am there brother I found out I am my brother okay okay okay yes yes yes Good voice etc everything is very clear what is happening we will tell you quickly then we will discuss and we will give this lecture today son we will start yes brother what is the sound she is very nice, sweet, beautiful, well behaved, how is she the sound is coming out good it is coming out good it's coming good it's coming good it is coming out great very correct very correct what it's done today that is Look at electricity brother electricity very cute very nice

1:36 Nanna Munna Sa has its own beautiful chapter But it is not as cute as it looks My son is bleeding from inside, why is this Because its questions come and you have to solve them It cannot happen, you say, brother, friend, that Brother, the question is about power, the one which is electricity consumed questions bhaiya that circuit Solving I said friend stupid boy fool boy one prashant bhaiya is here why to fear We will take care of everything, sit back and chill I am not feeling chill please bring the copy pin Today, Bhaiya, he is sitting comfortably like this I will teach you and you will see that you don't sit like this okay so chill chill means you are understanding right Chill means I have opened the notebook pen, tell me quickly Has everybody opened their notebook and pen? I have opened my notebook and pen, what is it, tell me quickly

2:22 Give me the pdf of the Gad series, hey team guys Please give them the PDF of the God series Children will cry Bhaya God Series PDF Brother give it to me brother see this cruelty with us One or two kids are still saying bhaiya did not open it why copy book You will agree to this will you agree come on take out the copy book ok now i First of all tell me in the comment Where do you find electricity Let me know quickly if there is a problem Where is the problem with electricity? friend, I don't know but it's still real These are the kids I can see, real kids yes but if it comes then it will come anyway physics Is the board also afraid of Physics today? It seems that Physics is not everyone's cup of tea Physics is physics physics is physics right

3:08 Brother, even the boat must be scared today Well, today I will have to study physics. How can I read it If the boat does not come then turn the boat around We will kill it today because the boat is from our house It must be that the boat is not from our place, it's ok yes Great, let's name the boat today Give the bot a good name in numerical Energy and power are becoming a problem Numericals are correct, Joule heating will happen today The law will be done, let's name it but If voting comes today then name the vote The poor guy takes the boat feeling embarrassed I may not be able to come back as I have enough very good what are these kids writing nallu what is this bro nall what would have happened

3:54 This is Pat's A, what are you telling me about the name of the boat? hey you are cbse will you agree even after getting beaten up Robot Vinod what is the matter yes son complete I will do the whole chapter I will do the whole chapter You can easily complete the whole chapter in two hours inside in a great way in a cool way We will do it with fun and enjoyment, there is a complete chapter No, it is a one shot, it will be in detail it will happen in detail, okay, whose will it be tomorrow Tomorrow there will be electricity but it is free ok ok a kid is writing aunt's name Boy or okay brother okay okay brother okay okay let's go now let's do the naming

4:40 we will do boat chintu chintu there is no red boat Chintu Lal is my friend, I will kill you Name the boat, [ __ ] Boat, [ __ ] Boat, come on brother Come on, when the boat arrives we will think about the name of the boat you sit down and let's go electricity let us start let us start let us start our chapter electricity with full ji with Full Josh with high power in the pole what is going on, what did the team give you brother what poll are you giving this poll given in the poll it's good ok ok ji ok let's go it's cooked isn't it Boat kids are writing pagi Boat butt is also saying these are wrong people They do injustice to me as well what do they do, they do it to me too we are playing the game of life

5:28 Let's start quickly with electricity With full energy and full enthusiasm you will understand, watch this Brother it is a simple chapter, it is very easy I am not able to do numericals, I know why I am not able to do it You become this because you are very afraid of what would happen isn't it when we are very scared Nor is it an obvious thing, we begin to feel that friend this is very tough very tough when he's not very tough he's not very tough It's simple, you just stay focused And keep listening attentively and copy Keep taking a pen and writing, you will understand everything It's simple, come on, let's do it quickly Let's start with electricity What are you going to read Electric Cha charge current potential is all this I will read all this, son, I will read this today itself All things law related to electric current Resistance Power Everything Done This Chapter It starts between three things First of all there is a conductor

6:14 One is an insulator and one is a semiconductor what is a conductor what is a conductor tell me a conductor is that which transfers electricity what does it do it conducts electricity i.e. electricity which has to be passed we give it to him lovingly and tell him that this is tell me is he the conductor isn't he? This is the conductor oh man here it is again This daily daily daily will not end today Neither their troubles will end nor brother, these people will not agree, these people who put Are you there These people will not accept the bot They will not accept this My friend is worried now it is he who is bothering us

7:00 We have reached the limit of peace I want to teach you see, no one can teach you anything from me I told you I will give you a very nice Let me tell you the truth, how much does one teacher cost? Kids are studying inside the class, right? Children it is very important whether No matter what anyone says, that's the difference with live numbers It doesn't make much difference to me and It matters to everyone that there is some truth inside no it doesn't make much difference why does it matter because 5 years ago today when I When I had started teaching, son, then there was a I was crying with the same dream that we will become this Indian Will be able to make a contribution in education Will be able to teach millions of children online I came online only with the help of Madhyam otherwise So you could have studied offline but come online What was it that millions of children had to be taught? So these are the numbers we have today

7:47 One crore children have watched the lecture That is no motivation for me The comments that come after this lecture That is motivation for me, so this fact I can't lie about the watching that happens No, it is very important for me and Reality is but real children's watching This is important which is becoming popular nowadays I don't know who is doing it in a few days and Even if I know, I won't say much but This is going very wrong for me It is important how many real children are studying because it gives a sense of I got the motivation to sit and work all night long. that forces so many children to have They are studying with us and trusting us Are you trusting us by commenting I am saying that brother I enjoyed reading it, brother understand it Bhaiya, I got my marks, that is my motivation

8:33 So I will never deny this fact I will bring it, it is very important for me It is important to me and will always be I am telling the truth, I won't tell anyone But I am speaking for every teacher this happens Important: Today there are more than 2 lakh users on our app Children are reading downloads in it 1 Million plus is a lot for me It is important because that is my This is motivation friend, but do it again and again They have destroyed all motivation It destroyed all motivation and there's nothing and nothing else Brother, you spoil my whole mood I want you to teach me real kids I have to teach everyone, I want to see you friend people to see how many children are studying but not

9:19 This has become their daily routine now friend what can some people do now who are then after developing that technology I don't know what ghost comes into my head that it does this Everybody does it, come let's go to electricity what happened first on electricity conductor then its semiconductor an insulator What is a conductor? Conductor is very simple The thing is that a conductor is something which carries current It allows the water to pass i.e. it flows easily this is how it happens son it flows easily It flows very easily, isn't it? What about us? He will be called his own, he will be called its conductor there are free electrons inside What is a Semiconductor? Semiconductor It is something between a conductor and an insulator that occasionally ignites the current sometimes it doesn't, whereas the insulator is which does not allow current, this is very It is simple, we study this even in lower classes Now we are done moving towards the main point

10:06 which is the electric charge We will start, son, let me drink some water for a minute electrical with electrical charge start your charge Let's see brother what is the electrical charge There is a charge which is incurred in this property There is a charge, it is a property, right? what is the charge if it is a property then it is a Properties of matter that cause its experience a force in an electric field, that is There is a property with the help of which a force Positive charge is being generated What do they do? They repel the positive What do negatives attract? Everybody would know this, right? So what would this be? you have an electrical charge what is the SI unit of electrical charge What is the SI unit of charge What is Coulomb? Now here we will tell you something

10:52 Properties are of charge which you One of these properties should be known Which question is asked repeatedly in the exam Let me tell you that too, don't worry, just chill First check the property you have additivity of charge means the charge which is It gets added, suppose 2 coolam on one body The charge is 3 coulomb and the charge is -2 coulomb If there is a charge then tell me the overall charge on that body How much will it be, you just have to add all three I want to take 2 + 3 - 2 how much will it be 3 coolam So this is the first property, isn't it? What is it son, what is this first property Tell me quickly Excellent next charge is conserved charge is conserved means the charge which is there will remain conserved i.e. charge cannot be

11:39 CreatedDocumentsFragment But the charge will never change, whatever the charge is The unit will remain the same, there will never be any charge The charge is invariant, the next most Quanta Emission of Charge is Important what is happening son what is happening Quanta Emission of Charge is a Property Which I will explain with a very good example hmm just imagine you taking a bath early in the morning You got up and said mummy said hey chintu Go and he is our confectioner right uncle yes Yes I bought that laddu from his shop

12:26 Imagine you went to uncle and asked him I said Uncle ji she me no Uncle ji please give me 23.3 grams of laddu I won't give you laddus but it will not give you anything to eat Will I make you a laddu, son, by beating you? He will say, hey crazy, have you gone mad, run away He will do it from here just like this, right Uncle ji will do it, what else will you do brother Because you can't ask for it like this Laddu you will say either brother give me 250 grams Give me either 500 grams or 1 kilo Give me two kilos or one fixed unit similar to buying laddu electron electron is a unit What happened to whom? This one minute is yes What happened that there was no response even for your charge Overall how much will be the charge for one body what will happen for you also there will be a unit i.e you I can't tell you how much the charge is bro

13:13 give me a charge, you will say it is an electron Give the charge of two electrons Give the charge of two electrons give me two or three electrons, give me four Give me five rupees or six rupees, like we are laddoos Asking for 250 g 500 g 1 kg 2 How do we ask for the charge per kilo in multiple of the charge of the electron i.e. Quantization of charge says that The total charge of the body is equal to n * e here but what is n n is the number and what is e charge of one electron What is the charge 1.6 * 10 Pa-1 coulomb Everyone remembers, remember, Abe Navi did not read it You have come without studying, you have come right did you not read it? yes yes very good ok

13:58 is it or So that means if the overall charge on any body If you want to find it, I have the formula q = n What is the number n i.e. its value is one it could be two it could be three It could be five or six, it could be any number yes but point cannot be integer the value will always be the same, then this would happen is your quanta of charge that which How do I get the charge? The charge is a multiple of the electron charge in multiples of the charge of the electron you may get charged now question on this How will it look brother, show me that too, take it brother look at the question how many electrons are there in one coulomb of charge in one coulomb of charge how many electrons are there will you tell me tell me how do you remember me I thought brother I will write it to you now

14:48 know there's a coulomb charge okay we need n we need to find the value and we know that the charge of an electron this happens ok so take it here if you go and find the value of n then do the calculation, the calculation is yours very strong I told you your calculation is very strong Sir, your wife told me Name is crazy, is it a little sa yes friend this is too much okay so it means one How much will be the cool of charge if this If you calculate, the value of n will be 6.25 * 10 rate power 8 elect what thing clear tell me quickly tell me quickly what is clear

15:34 this is very good this happened this happened What's the matter, just like that, with so much energy I am going to be full of energy, son Let's move on to electric current So now this is about your charge What is current, it is very simple Electric current is the rate of flow of charge the rate of flow of charge How much charge is being released at one time we will call it current i.e. current what will be the formula i i q bati hai na i i q bati as you call it do t like that i q ba t yes then remember it like this I will take it, okay I will remember it like this i i q baati

16:23 very good so what happened this happened View Formula of Electric Current Now Son, what is the SI unit of current Tell me what will be the SI unit ampere What would happen if ampere was the SI unit The current is in ampere A. let's denote okay now imagine paper I have a question about defining number two How will you define one ampere? Think about it. Will you define it, it is very simple, I asked it again and again also goes, that's why I am telling you whenever someone If you ask me to define and ampere then you can look at the formula and you see that when 1 coulomb of charge when one coulomb of charge passes will do it within a second within a second Then the current that will occur will be called 1

17:09 The amp is great right? Yes, when one coolant of charge flows in one second then the The current is supposed to be 1 ampere, what do you understand I came to those corners of my mind Have you reached, yes, yes, my name what are you putting puki in front of it, there are a lot of puki yes but it is pure so let's go brother boat bhaiya I am understanding that you are getting the charge current It is not coming to your mind oh my god You don't have any brains It doesn't matter, you are a boat, let's see brother Next let's see now there is a big one here This is an important thing that you should understand a battery which is not a battery a battery You will know what the battery looks like Now you can see your battery in this way Remember one thing, the two terminals of the battery

17:56 if there is one then what is positive terminal like this is positive and this one it's negative okay so always remember that it gets charged right charge charge which is your electron which is your electron the electrons are always negative terminal of a battery to positive it comes to the terminal and whatever is your current The current that I just told you is current, current is always from positive terminal to negative terminal Will I remember this thing? I will remember, tell me quickly, tell me quickly that always electron negative to positive but which is your current the current is always positive to This thing should be remembered very much it is very important ok very good why is it important because there is a Assertion reasoning question was also asked once

18:42 He went there, I will show it to you, look Read what question came in Assertion Reasoning Look what assertion was asked, this is of 2024 the question is maybe look at the electron move from lower potential to higher potential in a What is the conductor electron lower potential That means from negative to positive that means higher they go up to the potential is this correct What you just told is absolutely correct, see the next one Dry cell contains an electric potential Difference across the end of the conductor i.e. A cell which is present in a cell, at its end what happens in what happens at the end hey son tell me the potential at the end of it Is there a difference? Is this statement also correct? which is your cell, it is your battery Is there a potential difference at its ends? there is a positive and there is a negative

19:28 what happens is this true is it true that's right tell me quickly what is correct that's right tell me that's absolutely right but but but is this the reason for this is this the reason for this now read the statement back from electron move from lower potential to higher potential in a conductor because a dry a cell maintains an electric potential Difference across the end of the conductor i.e. A dry cell is one that stores potential Is it the reason he maintains it There is no reason, no weight, no relation Brother, the answer to both of them will be this Look, this answer must have been given by a bot too

20:13 If you get caught then this is what happened to you Assertion and reason are true but reason is not the Whoever has given the correct explanation You are absolutely correct, son, move ahead Let's quickly move towards the potential difference which side the potential difference Come to the side brother now what is this potential difference If there is a problem then look brother, just imagine there is a charge I have put the charge which is in a corner I said charge it if you come towards me came running towards me That means when that charge is taken from there to here If you move it then the work done in that movement Work done means you understand right oh ho ho ho nine So you did not read it, right? Is your work done?

20:59 Yes, the pipe is coming little by little Come in the wash, I remember the work that was done From there to here we get that work done It is called potential difference, that is if i am accurate about the potential difference tell me the definition of work done to move a unit positive charge between two points i.e. one I move a positive unit charge from one position to the If I take another position then the work done in it It's done, it's mine, what will you call it, it's mine It will be said that there is a potential difference, son. no son very good so potential difference The formula for this would be v id ba k i.e. work done bye say charge ok now in you Someone please tell me should I hide this from you Someone please tell me what is the unit of work done tell me what is it tell me tell me

21:47 tell me why are you turning the pages, don't you remember No, tell me correctly, I don't remember what a joule is. Joule Energy and Work Done Unit of Son Same which is joule a child is writing volts writing volts Is volt son where is my stick Volt hey volt how will you become friend what are you talking about friend, you are working so hard I am reading from here standing, you write volt brother tell me one thing how can the work be done This work is done in Joules and charging type is your charge gets generated in coulomb and The unit of potential is T hey volt volt yes very good good now

22:33 You define it, you define 1 volt Define it, you will do it now, look at the formula when will you do it when a one coolam of charge moves from one position to another and the work done is 1 july That means 1 joule of work will be done and the charge is how much is the charge for 1 coolam then The potential difference which will be generated when volts are generated It will be made, we will call it and it has volt, right? Joule of work is done to move a one unit positive charge between two points then the What is the potential difference called 1 volt? understood it quickly tell me quickly

23:19 tell me bhaiya paper leaked leak leak leaked is it leaks leaking leaks yes listen carefully i am talking to you Your English paper will be on 15th or 16th come on 17 come on 18 come on 19 Come on 20th and come at 4 am on 20th okay let's go ahead let's move on So brother, now the potential difference Let's look at a question of how much work is done in moving a charge of two columns Across two points having a potential Difference, why did you put this answer here? friend the kids will see what it is coolum across two points having a Potential difference is so much in these questions First of all write down what I have to do

24:05 what is given we are given charge is given We have a charge which is 2 coulomb and What have we been given? Potential given This is how much it is so what do we have to take out We need to find out the work done, how is the work done We will find out son, we know do you know the formula yes so this If you multiply this then the work will be done will go voltage into charge which will be 24 Joule Joule Joule Joule Joule Joule Joule Joule who took out joules, who took out a lot great very good very good simple It was a question, wasn't it? It was a simple question now. Let's move on to a next level question Son, the next level questions are going to increase All the numerical tricks in physics what is the trick it says that first of all You should see carefully that for you

24:52 what is given and then think of the formula and then solve it first given you have to write okay like come on let's ask a question hey friend don't give this answer friend Kids will get scared if they see the answer, right? Come on let's solve the question now, write it down I have given it to you, I have written it down I came and saw a current of 10 amperes flows through a conductor for 2 minutes He is saying now see what is given to everyone first look at the current one minute brightness is low do it or else half the kids will say bhaiya dikha I am not giving it, okay, take the current brother we are given 10 amperes what is the matter what else have we been given time is given 2 Convert minutes into seconds which will be 120 seconds now see son

25:39 What is given next, calculate the amount of Charge passed through any area of ​​cross section means we have to tell how much Will pass the charge? How to tell the charge How to take it out, son, tell me my friend How can you find out, this is obvious It is very simple brother, there is a formula for this is current equal to q / t right then q will become i*t so what did you get What did you get? These two got multiplied This is what you had to do fools how much did it cost 1200 Who all got 1200 Kulam, did it come or not? did not come came came very good came next see what's next if the charge of an electron is 1.6*10 rate power-1 coulomb

26:26 then calculate the number of electrons now What is the number of electrons saying? Tell me How will you tell me that you have it now? you know what happens Quantization Quantization of charge now you have 1200 so you and this is 1.6 * 10 to the power mai 19 now you just have to take it here and I have to do maths math math your math is very weak are you very weak in maths? child is writing prashant bhaiya cross cheetah What does the cheetah say to the lion? Only the cheetah says to the lion. what do you say yes ok brother very good That's good, so calculate it now. Calculate it brother, what will be the answer

27:12 7.5*10 ray power 21 ok It is very good, it has come, yes, yes, very correct very correct bhaiya which trophy where is the trophy which trophy is visible Which trophy did you see? what have you put brother wow wow brother okay Everyone has got the answer, okay let's go to the next one. Question hey friend i have answered it again hide answer The kids will see that he is a cheater, he is a cheater Come on everybody brother let's see brother everyone First what is a steady current of 5 amperes Flows through a circuit for 30 minutes i.e. I know brother the current number is five okay now what did I tell you this

27:57 how much time is there time given is 30 * Fools, do 60, it's okay, 1880 seconds are enough. right now what did you say, how much charge Circumvented through the circuit hey friend again the question came on the charge what is going on You just have to multiply both tell me, do it, talk to me, talk to me this much Simple, should I get this done? Should I get this done? Should I tell you no? tell me brother aa two gai is coming 9000 aa It is 9000 coolam 9000 9000 t is yes very good let's go next Let's see the question is coming now, look good

28:42 one by one a little bit na sometimes question a Different questions also come sometimes Some differences also come, right? Of these, those which are yet to come, which I have so far They will come to your level but I Let me ask you one more question of one level Son, one more question of a slightly higher level I will make you imagine that this is given to you that the number of electrons in a wire which You are getting close, see son, you have been given that the number of electrons is how much Are 3.2 no 3.2 I will not take it I will take something like this which makes it easier 1/32 * 10 rate power 19 what did this give you this is the number of electrons given to you, which that they are passing through a wire okay and And you have been asked about the work that has been done

29:28 That happened at that time, two July, so you The potential difference of this wire has to be told can anybody solve this question can anybody solve the question Tell me quickly what can anyone do in any Brother, a kid is writing to the boat as well Getting a chance to solve the question Do you want it, tell me if anyone has the strength to do it someone is show me your strength I am unable to do it I am unable to do it keep saying speak very good very good Look, what did you have to do inside it, son? you knew the number of electrons and you I knew the potential, look at how to find out the voltage

30:15 This is the formula, i.e. you will be charged I want to withdraw the charge, how to withdraw it from here There is a formula to find out the charge was n * e okay so number of electrons We are given 1/3.2*10 to the right power 19 right and what is the charge of one electron This means 1.6 * 10 to the power of -1 so + 19 -1 will be cut off from each other, son, look at the math Check the math, son. This will be 16/32 because I removed the points for both of them, so this came How much will you lose i.e. 1/2 of your charge That 1/2 has come, now charge it here The value you had to put has arrived 1/2 so this will be your 4 volt did the cha volt come, did everyone's cha volt

31:01 Came Say Tell me shameless people a boy is writing and Super Chat Bhaiya is anyone interested in talking Son, you know, I'll tell you a story. You used to be a friend of mine This is the story of a boy, that boy is not complete what was the time i used to play free fire all the time I used to live there during my school days, right? After that, someone kept chatting with him I did not pay any attention but he thought that someone Giving him attention, now the poor guy is chatting

31:47 I'm trying to get someone's number all the time trying to talk to somebody He is also being And the condition of that boy today, son He can't find a job anywhere The poor fellow is roaming from door to door, hoping that he might May he get a job somewhere Do you get such an opportunity to earn money? His condition has become bad and son remember this This is not a story, this is a lot of reality It belongs to people, it could be yours too Let's move forward with caution, on whom let's move forward let's move forward right electric side of electric circuit what is a circuit electric circuit attention So understand son, basically what we are going to do now

32:34 we're gonna do a whole complete circuit Design and make components of the circuit You will understand now you should understand this much that a complete What are the components needed to make a circuit? If we are going to guess then first of all their names Understand that your one cell comes first What happens is a cell has two terminals positive and negative terminal if we are very If we combine all the cells together then they what becomes of the son so he becomes What becomes of the battery? The battery is yours. Battery is called good, there is a question like this also It came that there was a 3 volt cell and such If a battery is made by combining three cells then What will be the potential of that battery? Tell me something You didn't have to do 3 + 3 + 3 which means you got 9 I had to write volts, okay, so make it like this the battery is done the battery is done son next

33:21 what comes your next comes your switch next comes your switch this is your If there is a dot in the middle of the switch, The switch is closed i.e. it is passing current If the switch is open then what is the current passing I am not doing it, it is very simple, isn't it for you All these wires at T point are of no use These are all wires, next one is yours bulb bulb you should know that the bulb it looks something like this ok Next comes the register register what Whatever happens, we will discuss it further. Register It is a device that provides resistance What is resistance, we will also discuss that further we will discuss okay what is this whenever one You may see such an arrow on the resistance no if there was an arrow like that then what would we call it son we call this a rheostat What is a rheostat? It is a device whose resistance we can change yes you can change it as per your convenience

34:08 This device is done, now the ammeter comes And look at the voltmeter, son, what is the use of the ammeter? I just told you about the current coming Who understood electric current? Electric current came, yes so Yes, to measure electric current yes to measure it you need to measure that current very good great very good for What do we do for that? We install an ammeter. isn't it and when do we plant volt peas volt meter to measure the voltage that brother What will be the voltage of the circuit Now remember that the ammeter inside It always feels like it's in a series it's okay in the series and how it always feels how does your parallel feel parallel It seems it will be done, it will be done, you will understand

34:53 okay so now we're in a whole different way make a circuit make a circuit What would be the most basic circuit that would have a There will be a battery and one wire will be connected to a bulb You will do it, besides that there must be an ammeter installed here But look son, an ammeter is always wire The ammeter will always be fitted with wire What will it tell you? It will tell you that the current How much is it? Will it tell how much is the current? Yes yes very good, what will this current tell you It will tell you and there will be a switch, what is this yours this is your correct switch if you need this circuit had to add volt peas inside then you know how to connect g volt meter always device K means this bulb which is in parallel with it will connect i.e. it will connect in some way like this I will show you how to make such a wire It will go up and there will be such volt peas here Such volt meter will be installed and connected to it like this

35:39 If it is okay then it will be installed in parallel like this A volt meter will be installed in parallel with this that voltage tells dun dun understand this till here If you come, please write PK in the chat once, brother Jaldi Jaldi Bhaiya RCB Vs C Bhaiya RCB vs CSK which one do you like? hai mumbai indian amchi mumbai mumbai indian has come but its ok First of all I also support RCB then I realized that this way There is only sadness in me so then I put my I have changed the route, okay come brother What is the difference between ammeter and voltmeter See quickly what current the ammeter generates

36:26 A voltmeter is used to measure A voltmeter will measure your potential difference It is used for measurement, always remember this In the series it always seems like what it is In parallel we apply it to a We represent it by v represent the next thing and many more The important thing is your ammeter His resistance is always low attention See son, the resistance of the ammeter is low because it has to pass the current okay so its resistance is less Bhaiya tell me now what is resistance I am waiting, wait, its resistance will reduce And the resistance of volt pea is always it happens it happens high it happens okay it happens high But Bhaiya Resistance Resist Resistance You keep saying it again and again, tell me what is this It happens once, we will be the first ones to come to it understand ohms law understand resistance Look brother, resistance is like an obstacle

37:13 the obstacle in your life is your life there is an obstacle that anything can happen to you I know I won't say it now, I will no but you know about your life I also know what the obstacle is What hindrance to your life can I I will not say anything, son, did you understand? There are many such obstacles in our life I am here, who will stop you from studying? Who is stopping you brother, just tell me and find out If it goes then it will stop the current from passing son, what will he be called, he will be called Resistance is a simple thing, so resistance There is a property of a conductor that resist the flow of charge what's stopping it from flowing what's stopping it He will say yes very good here it comes Oms Baba Oms Baba whenever the name comes

37:59 I fold my hands because Oms baba this chapter is so important brother I always have Oms Baba Oms Baba Oms Baba It is very important that Oms Baba keeps going on Jai ho, this is what I believe, look brother Oms What does the law say? Ohm's law says this Understand carefully that whenever this current passes shall hear the current through a conductor whenever He is passing current in this conductor The current will be directly proportional to the potential difference across that conductor at the same temperature means if you measure the temperature if you are keeping the temperature same then it This is a very important line, kids forgot to write it let's go to the definition if you are there If the temperature is kept the same then the current passed is happening and the potential difference is Both will be directly proportional now

38:45 If someone asked that bhaiya directly what is proportional then I will tell you I made you shine by hitting you I will make it directly proportional to what it would be It means brother if the voltage increases then the current This will also increase, what else happens okay now look at this proportional sign We create formulas to remove these We call it Ohm's law which is v = We did not give it v = aa what is r in this son r is its own resistance blockage and what is the unit of resistance Remember the unit of resistance what hey tell me brother hey tell me brother what Om what Om what Om very good very Great, okay son, now we'll see here. what are the factors that cause resistance bring impact that resistance

39:31 Due to which factors the butt changes Before telling you about that, I will tell you the graph I would like to show you that be careful son whenever Yes whenever we do a graph what happens is and in that we create an end potential Write it and in one we write the current and in another such If a slope is coming then what will this slope tell you Son, tell me what will this slope tell you? Will tell about resistance, why why will you tell me sir ji sir ji why will you tell me Why will you tell me brother what is inside it what is it inside this brother this is why will tell you because you know a graph that whatever slope there is you will get it in 11th you will read it, you might not have read it yet, it happens Divide this by this means it is telling v ba aa and v ba aa what is resistance

40:18 so remember remember Son, I have understood the slope of potential The current graph will always represent What will the resistance tell you? Resistance is very It will tell you good resistance, okay son Great, now here come the questions. How do I get such dirty questions? I'll tell you I see you I will tell you, I will show you, brother If I show you, it will happen to you too, yes brother had shown me one question brother solve it Do it and chat tell me tell me in chat butt butt is coming understand I am feeling butt, I am not able to understand

41:06 You are coming here, you are not in the right mind Many children are also giving wrong answer to this Now we are giving some correct information here the kids made a mistake the kids made a mistake because i told you don't be like this boat be like human you should have brain boat what happens to the bot that makes it like this By creating technology and understanding the mind of Joe Bot He goes away but you are a human being my friend Look brother, what mistake are you making? Look at the graph. Now don't understand one thing whenever a V's The graph will be the graph of v and i, right? Suppose a graph such that v is a graph in whoever is on top, whoever is on top Its resistance will be more will always be greater, say this is r1 or r2 then in this graph r1 is always greater

41:52 will be from r2 because it is above because this It is above but if I turn the game around with you CBSE and give you the graph, son Inverted i.e. graph of I and V is Aa and Ka graph and now give you this is a come and this is aa2 now kids will feel o aav to it should have been more aa2 should have been less hey you idiot you dodged the question I vomited and whenever I vomit then Inside this case the bottom one is more and the upper one is less i.e. r2 will be greater than r1 I understood it, I understood it in my mind he entered speak speak speak speak he is going away I enjoyed it yes it was very good son That is, son, look at the graph inside this, there is one

42:38 current and here is the voltage so inside this r2 will be the highest then what will happen then will be r1 and then what will be r3 so r2 r1 r3 tell me brother where is it which option is r2 r1 r3 so this is your d now tell me who writes c who was it, who was the ACC, tell me. who was it c yes that's right who was writing a C I will kill this one C come come go on, it's okay, then you should know this This is very important, I should repeat this again and again Questions keep coming, son, one by one Look what A Resistance Huj has said I graph is given below its resistance Tell me son what will be its resistance

43:25 What will be its resistance tell me how much is the resistance hey 42 hajj kids Are records being made in live butt as well? Now records are being made in boats too Do bots like physics? I enjoyed it, yes I understood what you are feeling today I never understood physics till today in class If you understand physics then you will know all your Have you taken your friends along too? Yes, I understand. got it yes i understood i took all my friends you came to class okay okay okay

44:11 Read it brother, read it, come and see what it is The answer would be very simple, you just look at it take any two points here But take this voltage as the value of voltage Take it from here there is three and current take the value f so at this point which There will be resistance, it will happen 3/5 so its answer will be son what 3/5 jo that whoever has answered this question very well very good very good you all are absolutely right I have answered, congratulations, okay, let's go Things are cleared till here, some more questions Son, ask some more questions, ask your question This question was saved, answer it quickly what is it look a circuit has a charged coolant moving through it in 3 seconds which is the electrical component in the circuit if

44:57 The present will show the current which of the following Do you think the option is right? Tell me what to say It is being said that the charge is two coulombs, how much is the charge yes son your charge is two coolam i.e. charge So you're given two coulombs and you How much time is given? 3 seconds How much time is given? second then the current will be q ba t which will be 0.66 means you can also write 0.7 by rounding round off to 0.7 0.6 must be coming ok so the value of current It is coming approximately 0.7 now tell me See which of these options is correct The ammeter will show the current of 0.7 yc ammeter It tells the current and nothing else except the ammeter

45:42 Apart from this there is another device which tells the current whose name is Gano matar b Gano matar It tells very small current, very small, okay Let go o 5 Lakh tat bhaiya Boat brother what to do I liked Physics today I feel Physics is good looks much better Brother, I have developed such a bad habit I need to laugh in a stressful situation I have gotten used to it, the same thing happens with you Is it not there, am I scared brother The study papers have come and still you are having fun You should not stop, same thing happened to you too has a habit of laughing even in stressful situations

46:27 I am in trouble now what should I do now so what should I do so what should I do what should I do come on come on brother Let's move on to the next question: A Register has a resistance of 5 ohm and a current to Ampere Flows Through It Finds the Voltage To find the voltage, two things are given: Ohms Jai to the law Oms Law, son, take it out easily. will you give me what happens v i aa happens son something You don't want to do this, do you want to extract the potential So you just have to multiply 2 * 5 And this will become 10 volts, this is very simple The question was so easy that it will not come in the paper it won't come easy it won't come easy It won't be that easy, okay, let's move on Let's move on to the next question Let's see the next question If you look at it once, the answers are visible, kids Look at this when a battery of 4 volts is

47:17 Connected across an unknown register there is a current of 100 milliampere It means 10 to the power of -3, right? 10 Ray to power-3 this is 1 milli ampere the value is ok come forward what have you said In the circuit the value of the resistance of The resistor means you need resistance You have to tell the value of current given and what are you given you have voltage given So the voltage is 4 volts and what is the current how much current is given to you in 100 ml Ampere so convert it to ampere 100*10 rate power-3 how much will this be This will be your 10 re to power -1 ampere ok now what do you need to do now If we apply the formula v i aa then whatever will be aa

48:02 Son, that will happen to you How much should you calculate, you have to calculate the current how much is the current 10 re to power it If it goes up then it will be your 40 is everyone's answer coming out to be 40 40 four hey zero stop it Brother, brother, these people are so crazy, what now? go before 600 will you take 600 capes what should I do what do i do what do i do what did I do Oh man, this team is crazy these might have gone

48:52 why are the team having fun why are you having fun why are you making fun of us brother why are you having fun look at the pole now Look, the poll is the real poll which happens is one tells you the real number now you are in the poll If you see, around 1 lakh children will answer If we give this poll then it is real Isn't it true that he tells me this is what I am telling you I'm telling you this reality ok i am telling you the reality ok do this as many children as you can see the real thing If you are a boat then you won't listen to me If it is a boat then what you are seeing is real, son go and leave the lecture once in a while and The lecture on light has been scheduled for that Go ahead and like and hit notification Go there quickly and turn on its notification Do it because that is also going to happen tomorrow at 5:00

49:37 If it is there then we will go quickly and what will we do with it If you turn on notifications, you will go right away And you will turn on its notification, go quickly Go quickly and turn on its notification quickly quickly quickly it's done quickly done done quickly Everybody has to do it, yes, everybody has to do it, everyone have to do it done it done it done let's do it right, then this type of questions must be coming Everybody has arrived back dun dun dun dun dun dun dun dun dun dun very good let's move forward let's move forward Let's see the next question, look at the state What does the explanation of the Ohm's law say That is the explanation of Ohm's law i.e. You will find the complete definition of Ohm's Law here. had to do and define the resistance Resistance was to be defined as resistance

50:24 What happens, there is an obstruction, right brother? What causes obstruction of the flow of charge and give its SI unit for SI what is the unit ohm what is it ment by 1 ohm resistance good if i Let me ask you the definition of 1 ohm resistance what will happen what will you tell me tell me What is the definition of ohm resistance? I will tell you, I will tell you, look at your brain, son Put v = ir1 aa yes or no yes or no yes then 1 ohm Resistance will be the resistance of conductor Neither the current flowing through the conductor nor the ampere and potential difference across it is 1

51:09 Volt when the value of both of these is not the same The resistance that will happen then will be very good. Then the resistance is will say ok okay okay very good very good great very good what happened am I visible or not What is black, what has become black, I can see I don't see it once in yes or no tell me yes or no tell me am I seeing hmm quickly yes yes yes okay okay see one Two kids are writing no, how many wrong people

51:55 okay so you have been asked the next question Draw the graph of an ohmic conductor and list This is an important feature, that is, what do you need I wanted to tell you there is a V I graph here I had to remember what a VI graph would look like This is how it is absolutely straight If there is a line from the center then this is yours Is this your V I graph? you have to remember okay son it's done it's done, come on, it's very right, very right, isn't it? Now let's talk about resistance On what things does it depend, son? On what things does your resistance depend I am going to do it, isn't it friend? What is happening? where is the black coming from now what is happening What keeps happening friend, I live like this I don't understand why I live like this daily

52:41 How will I be able to take these people if they don’t stop? So if these people don't stop then I will How will I be able to take daily live Dude how can this happen Let me read it brother why are you doing this friend It's been enough now stop it all Let us study in peace, why bother us You are there, it's time for the board exams Why are you giving me so much pain daily, friend? stop it now enough is enough Went Come let's see now what the resistance is, son Factors Affecting Resistance Which factors will affect you the most? The first factor is, look, you should understand it like this

53:27 Compare the resistance with your vehicle See, son, what things are your car covered with? but now accept my maruti-suzuki isn't it a fixed property like The car also has a property that the car How is the engine from inside, isn't it similar? Next thing, now imagine your car It is okay if you are going on the road, if the road is wide If the road area is more, assume that the road The area is very dense, so there is a lot of traffic

54:13 Tell me will it cost less or more, there will be less traffic It will hurt or it will hurt more oh brother obviously The thing is if the road is too much If it is wider, there will be less traffic, right? son yes similarly if my wire is wire if its area will be bigger then area of If the cross section is large then the resistance What will happen, the resistance will decrease Brother, if the area becomes bigger, the road should be wider If it went then the traffic reduced, what is the traffic Traffic is an obstacle, so is resistance If there is an obstruction, that means the area will increase resistance will decrease next thing if your road If it is too long then there are chances of traffic jam is more or less is more because the road If it is long then there might be traffic, right? So this means that when Th increases then The resistance also

54:59 It will increase and your final formula will arrive Resistance equal to ro a ba a ye jo ro yes it is ro isn't it we call it r a o ro We call this resistivities what is your viti son this is your Resistivities Sivi remember this is your resistance So the resistance will increase resistivity sense But if the area increases then the resistance will increase it will be less, very good, this is all here Things were explained, one more thing which is to check the temperature son, remember if you increase the temperature then What will happen is that mainly the resistance will increase

55:45 Mainly resistance increases with temperature What can increasing your resistance do to you? It seems to be increasing, done, done, it's clear Tell me quickly then solve the question start tell me quickly If it is clear till here then resistances came What are resistivities and material interactions Sanic property is inter-sanic i.e. inside there is property inside it There is a difference between every material that is inside We call it property What does resistivities do that affects the current It stops the flow and creates opposition, right? So what will happen to him we are telling him Resistivities i.e. copper will be different from iron It will be different for everyone, every metal will be different It will be fine brother come and see the difference Let's take what is resistance and opposition to the flow of electric current while

56:31 Resistivities is it sivi hey why write it upside down brother why did you write this upside down this definition was supposed to come here This definition was supposed to come here this definition was not there What is your resistance and whose? On what things does the length depend It does it in the area, right? Next does not depend on resistivities differential resistivities are known resistance exter is a freak exter Sanik means that it is outside property and also It will start to depend on things, then it is okay These are some main differences, remember the rest of the units Keep it in mind son, whose unit is Om But resistance is resistance Tell me with ohm meter did you understand this

57:20 yes or no 720 7200 children are studying Yes, the boats have also made a record today tell me the truth, are you understanding the boat, right? You were weak in Physics, today you understood it Electricity to all my friends I am bringing it but you are not agreeing, right? I got it, let's ask this question Now brother, a good question has come, now use your mind Son, I have to apply my mind to these questions I will not show you the answer, otherwise you won't enjoy it you come look a wire is a wire

58:07 What is A Wire of Resistance 10 doing? om is drawn out so that its length is Thrice its original length i.e. what did you say There is a wire whose resistance is it is 10 10 how much is it son 10 is one wire What is the resistance of your 10 ohm what has been done to him, he has been drawn out He has been drawn out, that means understand son we pulled him and we pulled him The length has increased take a wire and pull it Its length has been doubled, i.e. earlier its The length was l now the new length that has come is how much has come it has come two times okay now You yourself think that it is good that Thrice has been said by Twa I have not said this even, I have said thrice, I have said thrice

58:53 three times three times okay now you son yourself Thinking If we pull a wire and then what will we do if we connect a wire to it we'll take it and pull it and what will we do if you thrice its length Will it happen son, its area will also get three times more why will it reduce whenever we do not pull anything then pull one thing If the volume remains the same then the length The more the area of ​​the brain increases, the smaller it will be Let me assume that whenever we pull something If it is then the more you increase its length its area will reduce by that much i.e. The area which will be there, son, will be the new area, three will decrease by how much it will become three times it will reduce okay very good now what is saying find the new resistance What is the formula for resistance, son?

59:39 The formula for resistance is Ro l / a ok but new resistance formula What will be the formula of the new resistance? So the resistivities will remain the same, but they won't She keeps changing son, she stays the same, that's fine Yours is not like that one, the length is the same now whatever comes will come three times and whatever The area came how much it came three times less That's it, now this three will move up and overall This will come, this is what has come for everyone i.e. new times Of row a ba a and old resistance us given is the old resistance is 10 Here is all you need to do to make 9*10 It was your 90 ohm which came or everyone's 90 came Did everyone get 90? Tell me quickly.

1:00:28 tell me quickly Done done ok yes ok yes ok yes Ok hey team ji just put a poll and see How many of your real children are there in it? let's see the next one look at the next question next What is the question? It is important, son, understand it. what are you writing black black black black are you mad have you gone where is black The screen is coming on dude what are you talking about yes ok we will ask more questions about it Plastic insulation will provide clarity surrounds a wire having a diameter D end Length as seen in the resistance Off the wire would be produced by a

1:01:13 What should I do if there is an increase in Vat What should I do if I have to What has the resistance said to do? Decrees in a resistance if I resistance has to be decreased so what will I do what will I need It will have to be increased, tell me, it is obvious It is a very simple thing to understand, beta formula happens r e ro a ba a if i If I want to decrease the resistance then I Will the area need to be increased? Yes or No yes or no absolutely absolutely i.e. area i.e. Diameter because area is related to what is it related to the diameter right yes so that means I What should I do, increase the diameter B isn't it very good very good let's go

1:02:02 Let's move ahead and see your next question son here is a wire as a top screen Resistance R and Resistivity R Answer the You will get all the answers to the following questions I want to tell you what all things he is asking There is a wire inside what is its resistance r and resistivities to the resistance if the length of the wire is Doubled keeping the cross sectional of the area Same thing, what did I do? I just did it The length has been doubled but my area is the same If it is so then it is obvious that it is because of the formula So it turns out that if the length is doubled Then the resistance of all these will also double Did you get double or did everyone's double come, tell me hey Tell me brother I have come I have come very good come next see what happens to the

1:02:49 Resistance if the cross sectional area is half i.e. if the cross sectional area which is what should we do, let us halve it keeping the length same if I am cross sectional area means what comes out r row l / a if I will divide the area by half I will divide the area by half If I do it, this two will go up and How much is the resistance will go twice twa this twice tell me how much it will happen because this is it because it is cut in half When I did it, it went up very nicely Next up is What Happens If the Resistivities If there are change resistivities then the resistance will be that Accordingly, change will happen if resistances Mains will also increase if resistivities

1:03:34 Mains will also decrease, don't tell me if you understood then PK Write it down if you understand it, write it down quickly, tell me you understood it PK came write it quickly tell me it is coming very good very good very good very good let's go next Let's see the question at the top of your screen, son. Here it is, here it is, let's go, Copper The wire has a diameter of 0.5 AA end Resistivities * 10 rated power -8 ohm meter is ok brother he is saying calculate the length of the wire to make the resistance 10 ohm how does the Seeing the Resistance Change if the Diameter is Doubled

1:04:22 Son, what is it? First of all, write what is given. In given we have given diameter [music] 0.5mm okay the second thing is what have we given Resistivities is Resistivities * 10 Rate Power-8 This is what we have given next thing What do I need to tell you, we need to find out the length and We have resistance given Resistance Given is 10 ohm now can you calculate it from basic formula You can solve this using basic maths there is basic maths in this tell me quickly There is basic math in this, you can do it There is nothing in it, son It's nothing, it's very basic maths Look, apply the formula r = rho l / a no just remember one thing this is from diameter How to find area diameter first radius

1:05:08 Remove it and then to remove the area There is a formula, so it is calculative This is a question, this is a calculative question there is nothing else, so first of all What to do? First divide the diameter into meters. convert it because it was in AM Now convert the radius into meters took it out and then what did we do, we found it We have done the calculation using Sk Pa A Skr Such questions arise from calculations of such length No, it's okay, it's this long, isn't it? I don't get any calculation questions, it's ok It will work, so what have we done We took out the area and then we took out the length comfortably everything else is given okay what is its second part how does the Resistance Change if a Diameter is Doubled if I twin the diameter Tell me how the resistance will be

1:05:54 If someone tells you a question, then use your mind tell tell tell tell quickly tell quickly in a flash Tell Tell me it won't be doubled, it won't be half either everyone is giving wrong everything is giving wrong everything is giving wrong I am giving you my brain, you should have understood son What I said is that if I measure the diameter what should I do to the diameter what was the question, doubling the diameter If I double the diameter I'll give you a Tell me if the diameter is double then the radius If the radius is double then the area will also be double what is area it is pa aa sk pa aa

1:06:40 sk means here r is sk so the The area will be there, son, how much will it be The area will become four times i.e. area will be will be quadrupled and you know the formula Ro a ba a if my area is four If the multiplication has been done then my entire What is the resistance? 1/4 1/4 1/4 1/4 very good 1/4 is done ok 1 ba f It's time yes yes 1 ba f jo four Times is writing that too wrong no 1 ba don't make mistakes here Please don't make many mistakes here It is important, it is very important here But if you come back after making mistakes in the paper There will be a lot of problems inside

1:07:26 big-big I understood, I understood, come on brother, let's move forward Let's move on to the next question: Two Wire A and b of the same material having same length End A Diameter 0.2 AA End 0.3 AA R connected one by one in a circuit switch off This two wire will offer more resistance There is a wire whose resistivities are The length is same just the diameter is different so ask

…
