So in this problem we have to sit ups. So the first ways we have the emitter with internal resistance are a and we connect. It was ah resisted our and we have We also have the battery was internal resistance mar in the M Memphis Ah ee. So this is the first to set up, and ah, so we can determine the courage in the setup as expression. Eat You, Abi, are a plus. Our plus are right. And in the second set up, we simply have the extend o resist the R and battery and also the internal resistance All the battery. What way? I want to resist. Get rid off Sly. So, uh, s so we have the battery and we have the internal medicine's on the battery. So I see that the expression. So this is I a okay. And for this one Ah, the current has expression. The over our products are great. So ah, from this relation, we can determine equal. Aye, aye are a plus r plus are great. So we can just probably expression of the e into this expression and see that to this sequel. Uh, I a one plus are a You are by our plus r Okay. So as you can see that you are a very small then I eyes very close to I A and part B. So, uh, we want to make sure that ah ah, I ate the merriment off the eyes. Ah ah in the range of about 100% in the range of 1% off the true. Correct. So in that sense, we wear had set up the limits 0.99 the true kerr and I should be smaller. Well, you go to I a right all. In other words, we see that this this becomes Ah, I do. I buy I a should be smaller all equal to one by my point 99 And from the ah from this expression we see that Ah, I over Aye, aye. Also equal one plus are a do well by our plus our hurry so we can get in relation One plus are a bye bye are plus our should be smaller all equal to one over pointing out 99 So we can't Upton at ah are a should be so by plugging the video of the smart and the cups are. I would say that our extra base model equal 2.0 for 29 homes. So this also explains the Parsi. Why we need to set up the Ah, this is that makes me a video.

Okay, so I have put on here two pictures for the from the fear. So you will know why I do this. So they've been beginning with the first picture. Now the questions is that a meter e one reach Stan and Pierre strike. So between Mark here current, I want this is kind of you won. Okay. On dhe I want is equal to 10 meters. 10 emperors. Okay, right now on batteries have no oppression interest. Okay, so what is the recent are so we don't are so let us mark the currents here for reminding the current readings in each image is so late is considered this to be I too The dixon doesn't matter as long as you make him right In the end. Yes, our poor little suppose And I do goes Here's rece. Consider I took. It's divided as here. I'm here. Here, I want got here. I want God divided into two and I fought. And here I too got divided into these two on Didn't call this as I fight because this is measured by the field. This is my fight on. This is actually Mr by three. So I three okay, No. If you want to use your jobs loss off the easy way is to always begin with the positive side of the battery. Like this. You're missing the personal in this case, The boys. Your side. He's like this. This is no. In this case, this is the look. All this begin MIT the positive side of the battery. So that Rex is He's here. So for the first year, right, the battery first. That is 200. Now, where are the drops? So the first drop is a cross are right. So I want him to heart. So I won. Um Okay. Now, is there any other potential drop across the circuit? No. So this is the first in prison for the first time. And this gives us the value for are, which is a Culture 200 development in that is during Dior's. Okay. Okay. So yes, we wantto the second move on the 2nd 1st again, as previous, we write their potential on 60. Now, where is this Princess dropped. So as you moved here, So the first potency is dropped here, and the current across this is what I to so And this is in the negative bricks and the look. So let me write. It here is minus 40. I do, right? Andi. And anywhere else there is a drop in the water smoke. There is no resistance here, so no, there's drop. So this gives us the value off. I, too. Well, we're getting fittest. One malice for every look. That's good. That makes it easy. Trick operated then. So I didn't go to minus for this actually means that the reason that we supposed off to is actually the I was right. So actually, I do flows this way. Right this way. Paris would have been the other way. Can you do? That is what I wanted in the second here. Okay, so there's continue with the lute's, adding the prison for the rest of the terminal agenda. What is there is 1 60 right? So this is 1/4 Now, where are the Pulitzer drops? So there is no more drugs here. Okay, here there is a drop off for the 20 Armbrister and the current is I fight. So the drop is okay. It is in the book. It is in the direction of the currently is in that dress makes you look so Plus 20. I fight 25 right. So this gives me I five vehicle stoop on 60 by 20. That is eat. And here. Okay, I forgot. Do right. The unit here. That is empty. Yeah. Okay, so we have already utilized all three lives. Now what? We can neutralize us, and we have only calculated this is this was even This current was given this I do week operated on I fight recalibrate The Reese didn't need to find my three. And I fought. So for that, we can use the risen between the currents that you see, the figure we have creator. I do. And I wasjust that I won't get separated into two. And I pull. So I took this. I post will be one. So if you plan the bandages off, I want and I do here, so 13 equals two minus four times. I thought so. I pour should be 14 amperes, right? Also, the other reason is that I do device into a tree and fight so we can write I to equal stew. Are you three? Unless I fight right now off these we know I do, and I fight. We don't know. I treat so minus for close to I three plus eight. So this gives me I three close to minus well and piers. Right? So we are found I for Andi, I three as well. So we are were found all the remaining currents. So if you want the new can now draw the currents in their actual directions, so I want is positive. So this is as it is, Jane Amperes. Right now I do is negative. So active in this is this way on dhe the sanctuaries for amperes. Andi, I for is in the same Erickson. So this is a game 14 even. Look at the figure. This matter's very onesie. Look here, Said Jane goes from here Was from here they mix up and become party. Isn't it great to see? Yeah. Now what is it? Three. Now I free is a minus. So it is in the opposite direction. So it is this way. So I three is this late and that is 12 beers right on. And what about I five? So I find it is a gem. Peers positive. So our dixon off Warren was correct. So this is he championed. So that is what is very divine. The I mean, you're a fight. So we are done with the solution on this question. Thank you for watching.

Okay, so here this part is the amateur consistent off the coven. Ometer plus us a shot. Right? So the total resistance off this am ear, it's gonna be one over when you fight. That's what. This part tough one over one? No. Yeah. One over one. This for this part. So one over the meter should be within this one. So we have the m e. Her resistance a secret U zero point nine six two. So, for Brian. So the total resistance in a system, it's gonna be the sum of hear us in here, which is about everything. Point Nice six or so? The current just I'm Solvay over our if about one point five civilian. So for our B. Now, there's no mirror in your circuit. So the current a client current riel, it's just gonna be for this Oto. Here we go this far, So don't be the vote age The year the village of a battery if I just buy The resistance is self. So you just identify over fifteen only one point six seven and it's a little bit higher then the value with the ambulance. So the arrow it just there difference divide by the real value, so it's gonna be one point six seven minus one point five seven divide by one point six seven. It's about six under about six percent.

19.85. So we have these two setups here for measuring the value of a resistor. Um, and this one, we're assuming that our volt meter has some resistance that will make our measurement deviate from what you would assume under ideal conditions. And here we assume the AM eater has some resistance a non non zero resistance for the M E to hear non infinite resistance for the volt meter here. And we want to show that the actual resistance is given by, uh, these expressions in either case. So to begin with. And we assume that they're reading accurately. They just, you know, have some internal resistance is so the voltage is going to be the current through the equivalent resistance. Um, the resistance of the Volt meter is in parallel like this very night. It's Siri's doesn't really matter in terms of how the circuit behaves. Um, so then I so that this would be one over won over our plus one over the resistance of the won't be here. So then just be arranging this. We get the times that some of the reciprocal resistance is is equal to the current. But then, if we divide both sides by, uh, the end and subtract one minus RV. We see that we get what we're looking for here I over b on minus the are said to be over here, R b we know, Imagine even ideal hope Meter. But that are a meter is misbehaving. So the equivalent resistance in this case is the resistor plus the resistance of the M Eater. So then we see that the sum of the resistance is yeah is equal two The voltage is divided by the current. And so then the resistance of the resistor itself is the voltage divided by the current minus the resistance of the AM Butor.
