E1/E2 using potentiometer (individual cell method or separate cell method ) #12thphysicspractical

So hello guys and welcome to my channel, friends Myself Sachin Shukla and you are watching A2J practicals Friends, today I have brought one more experiment for you. So this is the 12th experiment in physics. So this is your experiment number 10. E1 by E2 using a potentiometer wire EMF of the two given cells using a potentiometer wire So basically we have to compare two cells So which cells do we have? Once we have the leg length cell And one we have a copper vessel cell We are going to use two cells here And this experiment is very easy, friends All videos are related to physics. Go take a look at it. How to write in your handbook I have told you everything. How to get 30 out of 30 marks in an exam I have told you everything. If you like this video, then subscribe to the channel. Because one subscriber means a lot to me So let me start the experiment So, friends, let me tell you one more thing. This experiment has been divided into two parts. E1 to E2 First, I will tell you the individual method. Another part And a sum and difference method Which I will make into another part In that I will tell you how to do it Friends, this is experiment number 10. E1 by E2 using a potentiometer And this is a very easy experiment. In this, we have to make a comparison. To compare the EMF of the two given cells Using a potentiometer What do we have to do for this? See this diagram The first practical we are going to do Individual cell method Separated cell method Separated cell method This is And second, we will do Sum and difference method So first, today's experiment We are going to do Individual cell method That is E1 by E2 Equal to L1 by L2 And this is a very easy experiment. All videos are related to physics. Go take a look at it. If you like it Then share it with your friends So let me start the experiment Now you have to see here This is a potentiometer wire. This is a 4-meter-long potentiometer wire. That is 100, 200, 300, or 400 So see This is your potentiometer wire What is this? You can see this So this is your potentiometer wire Now see, this is 100. This is 200 This is 300 And this is 400 How does it work? So from here From here Until the end This is 100 OK Up to where is this 100 After that, this 101 begins And until there it is 200 Then it starts from 201 Up to here it is 300 Then it starts from 301 And this is 400 Now we have to look at some connections. Here We have to see some connections. Now in these connections What do you see here? That your 4-meter potentiometer wire This is your A terminal And the other one 400 meters where it is OK So what about yours? Terminal B Sorry, 400 centimeters OK That is Terminal B. So you see here So this is your A terminal. And this is your B terminal This is your A terminal And this is your B terminal Now let's come here OK So you see There are 3 wires connected to the A terminal. One wire Is connected to E2 The second wire is connected to E1. And the third wire is connected to the battery So let me tell you What are E1 and E2? So E1 is nothing but Your Lagrange cell And E2 is nothing but Your copper vessels Let me quickly tell you about these two. OK This is your Lagrange cell In this The rod of carbon That is your positive The rod of zinc That is your negativity. Here are your copper vessels. The copper vessels Are positive And in this The porous OK Zinc rod OK What is this? Negative What is your zinc? Negative And the vessels Are positive Here as well The carbon rod is positive. And the zinc rod Is negative OK You understood this So here In the diagram You see The part of A Is connected to E1 And E2 Once It is connected to the copper vessels. And once It is connected to Lagrange's cell. And the part of A Is connected to the positive Of the battery So this part of A Is connected to the positive Of the battery This battery This battery's positive This battery's Negative So let me quickly Connect this part Here So that is your A point. A point is connected To what? A1 E2 A point A point is connected To what? E2 And E1 Copper vessels And Lagrange's cell So these two Are connected here And what is connected Positive terminal of the battery So this is the positive terminal of my battery So three wires Are connected here So I will join. All three wires Here Now, next friends Let's come to Our diagram So see E1 and E2 Are connected to K1 And K2 K1 and K2 Are our keys So E1's negative Is connected to K1 And E2's negative Is connected to K2 So E1's negative Is our zinc rod And K2's negative Is our Sorry E2's negativity Is our zinc rod And K2's negative Is our zinc rod So these two Negatives Will be connected To our keys So these two Are our keys So I will Connect the Negative wires To the keys And see I will Connect the E1 wire Here Now The wires Of these two Where are they? Connected So see The wires of K1 and K2 Are connected To the galvanometer And the wires of K1 and K2 This was your E1 And this Was your E2 OK So E1 and E2 Will be connected Here To the Galvanometers And the Positive So both Of the E1 And E2 Will be To the Galvanometers Positives OK So see I will Connect Both of What is it that we are supposed to see up to this point, Yafate? The battery's legate terminal is stored here at your place. On this, there is a binary variable, so it will also be connected. Remember, "sai" means "not" in this context, so "saiyoun" means "not existent." This is the rear. I told you at the beginning about your B terminal. You can take a common terminal. Like I'm taking this one here This common one Which variables will be connected? Which variables will be connected? of the battery Negatus What are we supposed to do here now? So balancing length They are in the circuit The child must have read it. But if I have this reading from you The practical one Tell me what needs to be done. You are getting ready for the board exam. You should definitely meet him for a short while. Balancing length battery design in the circuit This is your even. What is this, Farindas? Take the E1 exit at the interchange. So, in the circuit, how do you get E1? You will close E1. As you can see, I've closed this here; it's for E1. As seen, this wire is connected from E1, and E2 is kept open. Here it is stated that the balancing length when E1 is in the circuit You need to include E1 in the circuit, then find the balancing length when E2 is in the circuit. So when you take the reading of the second one, you will insert E2 into the circuit and remove E1 from the circuit. Just get the key for E1, and listen to one thing carefully When you connect E1 in the circuit, insert the key into E1. But when you connect E2 in the circuit, remove E1 and insert the key into E2. Now, what do you have to do? Since you've already figured it out, I've already placed the circuit in E1 here. I have turned on the battery and set it to 4 volts. Alright, let's conduct the experiment. I'll place the circuit here for E1. Now, here in the galvanometer, what is the null deflection indicating? 0 is showing, null deflection what is showing, 0 Now, please check the lying position anytime. Look here You won't see Filal, but I'll have to show myself. Look here What do you have to do? If you press against the side of the wagon with this jockey Then your galvanometer will show a deflection to one side. So it turns out our circuit is correct. What does this indicate? The fronts confirm our circuit is correct. You will always check this first So, what do you need to do? I have just balanced the length at E1 I have taken E1 into the circuit. Now, current is passing from here. When you place it here So this will show you a side deflection. But you must take this null deflection with you So, what will you have to do? Jocky will have to top at a particular place. You Take it up and carry it away. Over 30 A side deflection is visible But as I paste it here So a slight upward deflection has just begun to appear. And such is this one Now I slowly approach Jokey I'm feeling sleepy. There was a time when that needle, you know, that one It will be zero at so. As it will be zero on the front, that's how it will be for you too. is reading What am I doing to Jokey? I'm specifically taking these kinds of tops with me. As we have Zero will be read What have we kept for Jokey? We brought Jocky here From here to here, yours is a hundred Soda Durd le From here to here, yours What is hundred How many centimeters have I advanced around 100? I've come close to 100 28 centimeters So how much will this be for me? 128 Once again, I'll check it. Alright Sorry, this is mine. 135 34 How much is this, friends? Because after one line, the second line on My jack is a tap deflection. So, how much will my first reading be? 134 My First Reading This wasn't written by a child. So, my received 134 Alright What do you want us to do? balancing length when E2 is in the circuit I mean, you have to take E2 into the circuit. And what should be done with E1? I'll close E2. I have taken this out here from E1 Leklancha Sil Wala What should I do with the copper vessel? I've closed the copper vessel. What I'm currently seeing here is the deflection Pipe deflection You need to tab it here If you turn the tap, then whatever your gallonometer is It will show deflection completely together. But you keep inserting such tabs intermittently What needs to be read? Check it. There comes a time when you I found this here. 9. How much have I read from there to there, and how far have I come here? It says 100, and where did this 8 come from? Sorry, friends, where did this come from? At 8, it became 108. Okay? So let's check the distance from here to here. How much is 8? So, the reading here, the second reading, how far ahead is it? 108. Okay? I have to do it for this second as well, for the third as well, for the fourth as well. How will you do it for the second? Baba, if you connect the balancing length E1 into the circuit, how do you connect E1 into the circuit, friends? What will you do with E1? You'll close E1's key and open E2's key. Come on. What am I doing here? Let's see, what is the key for E1 now? It's open. So what should I do with E1's key? I'll close it. What should I do with E2's key? I'll open it. Now I'll take the second reading from here. One more thing, friends, if you ever take a second reading, what should you do slowly, slowly? You will keep moving forward with these small steps. Don't keep reading this constantly. If you take the third reading, we'll go slightly forward. If you take the fourth reading, we'll go slightly forward. Matlab, slowly, you'll have to do this step by step. Okay. I'm tapping again right here. I will tap, I will tap again. Show me a reading on one side of the galvanometer. But there will come a time when I touch this, and what will the galvanometer show? When the galvanometer shows zero deflection, what should I do with that reading? Write it down for a long time. So, friends, what all have I provided here? As I'm keeping it, approximately at line 184. How much is my galvanometer showing here? It shows zero deflection. Can you see it? What is the galvanometer showing? Zero deflection. What is my touch here? 186 What is the touch? 186 To me, how much is being given here? 186 pe me What value is coming for E1? What needs to be done for E2? Open E1 and close E2. What should I do with E2? Close the copper vessels tightly. I need to remove E1 from the circuit. I'll keep tapping it, tap tap tap. I'll check the reading to see how much is coming in. Nothing is happening at all, finally. Nothing is happening. See you Here, take a look. It is showing a philal here. How many shows is it displaying? How much reading is coming for me? 166 166 pe null deflection is being shown here. The reading that comes here to me How much will it cost? 166 Here they come, for the third time What do you need to do for the third one? First, tell me what you want me to do? Halkasa, I'll give it to you The rear strut needs to be loosened. You need to move the rear strut slightly. What do you need to read? I need to check. What have you done just now? I have slightly increased the resistance. What should I do now? I will keep E1 closed. Since I need the value of E1. He has closed K1. What have they done to K2? It has been opened. I'll keep tapping on this. Where else am I supposed to tap? As long as I don't get a deflection of 0. After all, I can see that you are I'm tapping, tapping, tapping. As soon as I get a value of 0, then What am I supposed to do right there? I'll stop it. So finally I get here 0. Finally, friends, I will get here 0. Zero deflection. Got the third reading here? 274 Now let's see what That's ours now. E1 number 274 How are we going to get rid of E2?.localStorage.setItem('user', JSON.stringify(user)); Sorry, how are we going to get rid of E2? You must keep E1 open. What should we do with E2? Just close it. You have to go while tapping your feet. Wherever this value appears to you It will show 0 on the galvanometer. What do you want me to do? Just wait a moment. Friends, I touched here. How much am I getting? That is 0 deflection. For 0 deflection How much reading do I have here? That's your 100. It will be yours, 200 201 How much will it be for your 201? To you, my reading How many will come today? 201 Ab Let's do it for the fourth one then. Let's just do it as the last one. To make the last one a bit stronger, please increase the resistance slightly. Oh Oh, so you mean reading, like checking and checking? Deflection should be shown on both sides. This one side and this one Side deflection on the other side I am calculating the reading here. You have to go while being tapped repeatedly. Wherever it shows 0 What do you have to do? Just wait a moment. So Philal, ye mera jo 0, where is he pointing? You're reading, she's coming, 313 Fourth reading Stay 313, what's the meaning How will we figure it out? I'll open it for you, E1. What should I do for you? Open it and what should be done with E2? Close it please When you close it, you'll get this reading. How will it be obtained? What do you have to do? Go by tapping. There will come a time like that again When it shows null deflection To Is it coming your way? How much value does it show when you tap here? I can't see it. 0 deflection How much will it be for you? 200 243 How much will 200 be? 43 How much will it be here for me? For 313 243 To hum, dividing it would We need to divide this. I had met him earlier, 134 divided by 10 134 divided by 108 equals approximately 1.2407. How much will I get? 1.24 Like 1.24 It is here The second card is played 186 divided by 166 Will it be given to you? 1.20 Shall I write it here? 1.120 1.12 How much will the third Hume kit be? You can divide it. 274 divided by 201 Here we will get 1.36 1.36 Now, what is the last one? 313 divided by 243 So here we will get 1.28 So 1.28 If you don't want to take the trouble, then this trouble won't come to you. Adding everyone Divide by 4 So we will get 1.25 So what I mean here is How much is being received? 1.25 The EMF of my cell Matlab's EMF for cell I have also measured this one, E1 and E2. That's the value that will come out. 1.29 voltmeter measures the main voltage A multimeter performs main measurements. That's all How much battery supply did I take for the EMF? 4V What is its voltage in EMF? The values of E1 and E2 are 1.2. His 1.04 You can measure this with a multimeter. The one who is the most superior It is an indivisible method. That indivisible method You also have to do it just like this. So friends, this inseparable method In that portion, I have I have recorded the video. To watch the full video Don't forget to check out the doosra video as well. That is the sum and difference method. You will also receive the result. To watch the full video You both watched the videos. Are there two videos on the channel? Please go there and search comfortably. 12 videos, mail list, you'll receive both videos Experiment No. 10 of Sum method, difference method, indivisible method Friends, did you see the experiment? How did I explain this experiment? For making videos like these, I need a lot of props.
