To determine the resistivity of two wires by plotting a graph of potential difference vs current

It's going to eliminate your battery. The raw life I'm going to show you, you can just glance at it through the thumbnail or topic, and you're already very sharp. So, regarding this half-yeard old Yant, it was the Pratap clan. It still remains alive even in the most difficult times. One or two or three wires, however many wires you are given What can you do with your registration here, find out. So how do I find out, I'm not going to take those lectures here. I'm going to give you practicals here, so you don't need to go anywhere. Because this channel gives you practicals in the best way possible. Alright, so the goal for today, basically, you can see here that is, our aim is to determine the resistivity of the two wires It has to be done for the Portico graph, when you all will know That this 12, this is the examination number post. What exactly do you need to do in this? What you need to do here is basically find out the resistivity. with your R with your R Reply R And whatever area is yours The area we are going to use here The resistance we need to find out I must have some wires here. You will be given them at your college. I am going to find out the filament resistance of this wire. So, this is how it will be; I will tell you everything about it. First, I focus on the formulas. So, area is nothing big, just water. Area, Souri yeh From this, I can extract the length. For the area, pi and square mean what ours is This is Area Prose Actions. Screw gauge that you saw in 11th grade This is a material of this kind, right? I'll also find out the area right here with his help. Like the radius that is mine, the diameter of this war By draining the fund, whatever radiation I can drain, I can drain the fund. Now, instead of the diametrical paracostal 2, in its place I am I'll use constant, this is R, not R, but your radius is You would know that removing VYAR will require a lot of diacritical representation. After that, a graph will be shown, because the graph will display these things, since what we need to extract is here, the radius of the circle. Everyone knows this formula, Ohm's Law. I'm writing it down here, so you'll all get confused and wonder what the sir has written. Actually, this formula—Ohm's Law—where did it come from? Everyone will remember this. Now, look here, in Ohm's Law, this formula is... After drawing the circuit, what should I do? First, according to Ohm's Law, I will calculate the potential difference and current, whatever values are given, then plot the graph, so that I can determine its resistance. For this, first I need whatever values of Ohm's Law are given. If there are negative terminals, just understand this here— I'll handle everything for you; just wait two minutes, let me know, it'll become positive, and what about the second one, will it become negative? Now, from this very same source, from this very same voltage... What will be the outcome for someone? Am I ending here? What is the second one, the one that becomes an ind? That is beyond your scope What happens with negatives? Connect now What happens to the negative terminal of a voltmeter? Looking, staying It's the other terminal. What happens to the negative of a voltmeter? Your connection will be established. So, what about this way? We will make your circuit diagram here with Om Slo Okay? Okay? What are we going to do next? After that, we will look at some observation tables. Where we will calculate the least count of Worldometer and ameter After that, I went to Worldometer How much is the value of his remitter too? Whoever comes to me I'll fill the appa, I'll show it to you How to feel it They will calculate. And then we will plot the graph What will we get by plotting a graph? The area of the pie chart section—well, you can calculate it as Pi times R squared. I'll tell you how to do it. Now, let's quickly go through the practicals. I've given you a quick revision. Now I can move on to the practicals, so please pay very close attention. Here is one of your items represented in millimeters. We need to have today's Aameter in Ajijeh. So, in the amateur, today's ajijana is needed What does Ten Dasha Tō Magas Rī mean? It has to be multiplied. Have you seen the farmers, completely exhausted, the field boundaries too are exhausted. So that you are not left behind, our amibar is taking the lead in steady progress, overcoming obstacles to move forward. As it takes 2 hours to complete, don't you think it's worth it? For its role, the Metur was what I had from zero, so the living dead. What was it? From 0 to 100. How many divisions are there from 0 to 100? 10. 10 divided by what? Whatever number divides 100 by it. So how much will you get? 10 will be given. 10 millimeter. Now tell me, what would you do to convert from millimeter to meter? As you divide this by 1000, your answer will appear in amperes. So your answer will be 0.01 ampere. So, your list count is done. What happened? List the count of ameter. Second, you have a voltmeter. Now, in this voltmeter, let me also tell you its list count. How would you calculate the list count for this? So, from here, between 0 and 2, there are 10 divisions for the child. If you calculate between 0 and 2, there are 10 divisions here. Okay? And one line which is 0.2 of it, If you calculate, you'll find out. Okay? Alright. So, list count, list count of voltmeter. How would you calculate it? Tell me? Alright? Let's make sure everyone understands these points ahead. Then you will also get the list count like this. I have a wire. Okay? What do I need to do with this wire according to Ohm's law? Resistance will have to be found out first. Then we can find the resistivity. Let's do it. You will now see the circuit diagram. We make the FATFAT connections according to that circuit diagram. What was it, tell me, quickly? The one that was your positive terminal, Sorry, the one that was your negative terminal, Tell me, who will it connect to? negative of millimeter So this is your millimeter, So, regarding its negative terminals, Who will it connect to? from the negative terminals of the millimeter OK? What will happen to its negative terminals? It will connect. OK? Now, listen carefully to this, the positive terminals of the millimeter Who will it connect to you? From the rear source. Okay? Come on, let's make a big connection. Alright, buddy? So, to see such practicals, So, go ahead and mention such practicals. It seems like a lot of effort is required. One of your subscribers for this channel, It keeps me quite awake. So please try to do something. Connected? negative terminal, positive terminal Connected to one of the rear sources' terminals? What remained of the rear source now The second terminal, right? So now, the one that remained from the key's second terminal, Listen carefully, This second terminal of the key, It will connect to your device. from the negative terminal of the voltmeter, And the positive terminal of the voltmeter, It will connect. From the positive terminal of your battery, right? Now listen carefully, Now in this same one, This wire is not in these terminals. They will be connected to the positive and negative terminals of this voltmeter. So, pay close attention, How am I connecting here, okay? Come on, check this out, I took the wire. The one whose resistance I need to find out OK? If you're enjoying these videos, Please subscribe to the channel. Okay? Come on, now take a look, the positive of the voltmeter Who will connect? The positive of your battery eliminator What exactly do you want me to do with it? You need to connect it. What now? There's only one connection left. Look, This key here, The second end of the key It will connect to your device. From the negative terminal of the battery, Okay? Okay. All this connection has already been established here. properly Once you see it, OK? How will we see it? Look, this battery has two terminals. positive, negative the negative terminal goes to, from the negative terminal of the millimeter, From the positive terminal of the millimeter, goes to from the first variables of the rheostat, second variables Which will connect to your key The second terminal of the key, negative negative parts of the battery from, of the battery, will be connected to the terminals of the voltmeter, And the positive part of the voltmeter, It will connect to your device. from the positive of the battery, Now, the wire that you to find out resistance Exactly parallel to this, in parallel with the voltmeter Many times, look carefully, You will be asked questions in the viva. when you apply Ohm's law, Where is the voltmeter connected? Where is the ammeter connected? You'll have to remind yourself, A voltmeter is connected entirely in parallel, is connected And ameter absolutely in series, is connected Come on, What do we do? Tear it apart, let's turn on the circuit, What does the circuit do? I've given up. Alright, After you turn on the circuit, You must stay focused. That you know the key very well. Pressing is fine. You must put it in properly. After putting on What should I do with RehearsTod a little bit? I'll check the reading in it. You're telling the truth, aren't you? That's correct. I'm checking this here. Now you will be able to see here Look, the voltmeter shows something or other. It will show the delay. And even in that justice, our millimeter has something You have a defect It will be fine to see it. You will find some displacement, even in millimeters, just to see you. Now, children, listen and watch carefully. As I, look, this is your voltmeter, this is your milliammeter As I gradually increase the resistance here inside the body The reading in the voltmeter will change now, one way or another. And what will the reading be in milliampere? Will it change? Now listen to meditation Here is the line corresponding to the voltmeter. It's 0.2. I showed you how to calculate the Liss count. Now show it here What am I going to do? Resistance to You can convert this into amperes. How You will divide this by 1000 So So what will you get, 0.05 ampere will be obtained, Tike You can convert milliamperes to amperes, let's go. Now what should I do? I'll move forward with it, I'll take it at 0.4 So, here it is, your 0.4, one digit, and I've gone further, and here it is It's coming in at 90, how much is coming in for 0.4, 90 PropertyChanged, vaccine, what should I do now? Vaccine, now listen carefully, 0.6, Vaccine, now it has become 0.6 For 0.6, what reading is coming in the milliampere meter? 120, syringes for 0.6, what should I do, 120 ml emitter, syringes Now I proceed further, looking at 0.8, 0.8, vaccine, now for 0.8, How much reading is coming in the emitter that's connected, Tadi? 170, vaccines, which became 0.8 bold, 170 ml bold, vaccines Meli Amper Alright Now let's look at the forest. I will slightly expand the restaurant. On the tree The one coming to my reading Here it comes In the voltmeter On the tree How many readings are being obtained in millimeters? This has become 2020, how much is it coming for 220 to 1? For 1 volt, it's coming out to be 2020 millivolts. Now let's look ahead for 1.2. Because for 1.2 1.2 For Waldo The reading in millimeters that is coming here She is coming for 250. 250 millivolt For whom? For 1.2 Waldo Okay? Next I'll take a class for 1.4 Me For 1.4 Night Seven This is the Lint Yon Pae. It's coming by 96 or 97 Linth of the War How much will the child's weight increase? 97 How much has the warp increased? 97 centimeters Later, I'll have to convert this into meters. You need to write in this unit, understand the vaccine. Now after that, I need to measure the diameter of this wire using the micrometer. What did I have to do with this Gabin wire? So, what should I do for this? I'll use a screw gauge, right? You have studied the screw gauge in class 11, haven't you? I made the practicals really well, dude, you should definitely see them. The screw gauge is still a popular practical. Now, watch carefully how you should use the screw gauge. Alright, look, this is your sketch, correct? mark particular school principal filament Joham saved a little money, but there is a difference in the amount. him Pick a to exchange for me, disease pgax car is 0 km biv Pick a to exchange trend reignance Finished over his a Muscle audit Changbat Peter to en handler And the one inside the gear, he touches it somewhere above. So, your positive error in November is yours What is your positive error? There is a negative error in this cruise wave. How is it coming out? Look here. As I close this completely, and the spill has spread further, the father has done more. So, this zero inside the linear scale, this zero here What is this circular thing doing here on this site, exactly? Touching The vernier caliper with a circular scale, right? Zero with a Joo Linier scale. Wherever it touches. Who will correct your negative error? And brother, if zero goes down So the one with the linear scale Zero Ego, wherever you touch, that will be yours. That would be a positive error, but then there's an error of 14 today in it. What is wrong with Fix 14? This is an error. How do you calculate the Liss count now? So, listen, Lisa Count, I'll tell you about it. So, 0.01 millimeter is the liss count. 1 millimeter Look, for a circular arc... When you rotate the circular object... So, a circular cutter for turning... Vaccines? A line will make you feel restless. A line from the great ones, one for you... It will begin to appear... What will you do with it when it reaches 100, rotate it? So that's your one. One percent means 1 divided by 100. I mean, you have a circular one A line, linear line to show What needs to be done with 100? It needs to be rotated. So, if you divide one by hundred, that is 0.01, what will happen to this? What will be its least count? Correct, you can calculate it like this. You must know, you can also watch my videos, come on, now mine Whatever work there is, I'll do it; what do I have to do with this wire? What was 32? If you multiply it, how much will you get? It will be yours, it will become yours, that is 0.32 millimeter 0.032 millimeter Now we don't need this here A negative error was obtained, a negative error was obtained, you received You must know how many negative errors were there—minus 14, correct? So minus 14 times our least count, how much is 0.01 Vernier and this screw gauge now You will get it if you multiply. Minus 0.14 millimeter. What should be done now, sir? What should be done with the diameter that came in this? Minus means 0.32 minus minus 0.14, right? Now, this What will minus minus become, child? Plus minus minus what? It will become plus 426, it will become 324, it will become 314. And this will become 0.18 millimeter, correct? So What was the wire's diameter? 0.46 millimeter, correct? So, kids, you all have seen the experiment How is it practically performed? It's very important for you to create your journals, so look here You know, I've taken the voltmeter's list count. How many children know that? Can you tell me here? That is 0.2 volts, correct? And the second one, I had taken it out. It came to 0.01; after that, we took out 3-4 sering. Exactly, the first thing that came to me was the voltmeter reading I had taken that is 0.2 volt, 0.4 volt, 0.6 volt, 0.8 volt, 1 volt, exactly 1.2 and 1.4, beyond that is mine Right after that, for 0.4, what was our value? Our 90, so it will be 0.09. After that 120 came, so it becomes 0.12 ampere; afterward, mine came 170, which is 0.17 ampere, the one that came after was 220, that is 0.22 ampere; after that, 250 came, that is 0.25 ampere and the last one you received, 300, 300 out of 1000—I don't know how I'm doing this, but I got 250, 250 milli ampere, so to convert this into amperes, I'll do 250 divided by 1000. Okay, so how much will it be? 0.25 ampere. Okay, let's go on to this one too. If you're dividing it, what you're getting here is 0.30 ampere. Okay, now I've got it. Now, what do I need to do with this? Tell me, what's left? I need to plot a graph using these two values, only then will I get the resistance. Okay, let's see how to plot the graph. It's fine, I need to plot this graph, so please plot the graph according to these values, it's okay, just plot it correctly. Why would Vishaya, because Jivi can obtain what is received 1.05 m And if access is an issue 0.1 Vault Priké JB, I'll plot the graph clearly. The one who is clearly mine Alright then if One who is 0.05 So what will become of me, O life? 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 It will be 10, this is 1.2, 1.4, 1.6, you can take it from here You see, I'm giving you a step-by-step explanation from the help of the scale, and also one by one, a best explanation of a graph. So that you understand these things very well, if children don't understand the graphics, you can simply skip the video. If you find the video helpful, please like the video. A child is fine, but such actions won't work. These teachers are putting in a lot of effort for you, using one practical smart board and all the experiment data, everything. It will happen after that. After that, it will be illuminated. It's 30. It will go to O. One pint will remain here. One put, what will remain with me? It will also go to 3,0. Several times, this has happened to me. From here, I've taken one straight line. I have to pass, I have to pass, so please look very carefully at how I do it. Shabu passed it over, but they just kept watching as the power pool took it. I'll make two columns for two slogans I'll take two points. Come on, let's see which points you need to carefully observe First, I'll take the 1.4 one. This one is fine, the one with 0.9 Something will begin from here Alright, and this is here. A minus The slogan will be slightly messed up. Bhaya We had one forest What did I have on the forest? Alright If this is the first time What is my VIT? 2.4 It's only 2.4, that's all. Look, 1 - 0.4 And what current do they take? This one? What is your 0.22? What is 0.22-i1? 0.09 If you subtract this, you'll get it. 0.6 divided by 0.13 equals approximately 4.615. Alright, if you deviate from this, you'll get it. 4.61 ohms Alright, so this will be the value of resistance. The value of the resistance of the wire I had connected What will happen at 4:16? Remember this thing. that you Plot voltage against current If you do not plot current against voltage, it will go to the reciprocal resistance pool. Please clarify these things very clearly, I'm telling you again from the beginning. Plot voltage against current, which is potential difference versus current. It's correct to act on this plot, isn't it? Otherwise, it would be a very big mistake. Alright, clear, everyone seems to understand. Tell me here how much resistance I have got. How much resistance did I get from Omshlo's calculation? 4.66 Here, I've obtained the resistance; now, this resistance I can use the formula to find out resistivity. My resistivity formula says, look here Alright, I'll just place it upright here. I need to calculate the row. What will happen? Now looking from Zyan, I've already gained resistance. How much has been collected? 4.66 Everyone knows about Pi, the whole world knows about it. That is 22.7. After that, me I don't know, or perhaps I'm not aware of it A niche Tell me the diameter if that's what you got. 0.46 It will go to Diameter. It will have to be done together. So how much will it be? For this, zero point two doubled is four, two thirds desire Millimeter, that's fine. This will come out this much. What do you want from me? You have to enter the value of the radius here. If it becomes necessary, let me show you what I did. First, look at this—this is what happens. It's your free toja six, free toja six becomes, okay, and the rest I multiplied everything, and this is what I'm getting. Okay, and later on If Caraki is charging it, how much will the app get? These balances, I have checked them all and placed them here for your service. Santi meter came in, Lendh meter, riding now big, when you come this way You would have received this until then, after that, what did I do? After that, I shifted the point. How did I shift the point? It has been taken over there, and 10 to the power of minus 4 becomes 10 to the power of minus 6, okay? So this is the answer. You're such a big deal that you'd have to think hard to even bother with Kalikshins, right? Okay, if you're interested in this Pediap, just let me know in the comment box and I'll put the Pediap in the description—then you can get it from there. You were here, but regarding restivity, this is the better living WiFi restivity. Please, for restivity, you are welcome. What will happen to my resistance with this wire? You'll really like the practicals I can hope for so much from you And if you're live streaming this video
