For the circuit shown find the current in each resistor and the current drawn from the 40 - $V$ source. Notice that the p.d. from $a$ to $b$ is $40 \mathrm{~V}$. Therefore, the p.d. across each resistor is $40 \mathrm{~V}$. Then, $$ I_{2}=\frac{40 \mathrm{~V}}{2.0 \Omega}=20 \mathrm{~A} \quad I_{5}=\frac{40 \mathrm{~V}}{5.0 \Omega}=8.0 \mathrm{~A} \quad I_{8}=\frac{40 \mathrm{~V}}{8.0 \Omega}=5.0 \mathrm{~A} $$ Because $I$ splits into three currents: $$ I=I_{2}+I_{5}+I_{8}=20 \mathrm{~A}+8.0 \mathrm{~A}+5.0 \mathrm{~A}=33 \mathrm{~A} $$
And this question we are given a data of the current and voltage. Okay. And they need to find the resistance of this circuit and we need to draw the graph between I envy. Okay so drawing the graph between I and we is very easy. Okay if we just throw access. Okay let me just draw the excess. Let's say this is the voltage. Okay. And let's say this is the current. So if I just draw the points. Okay. And I just draw the points here. I suppose this is 2468 10 12. Okay. And let's say this is 1234 and five. Okay so these are the points. So if you upload the points in the graph it comes out to be a straight line. Okay so the graph between iron B comes out to be a straight line. So if you look at the slope of this function, okay, slope of this graph. It comes out to the eye upon we Okay. And we know that resistance of a circuit. Resistance of an atomic circuit is given by we buy I. Okay. So we can say that the resistance of this circuit is equal to one divided best law. Right. So we can take any two points between uh on this graph. Okay, let's say I have taken this point and this point A and B. Okay. So from the given data you can take any two points. Suppose I I am taking the first two points. Okay, The one and this report. Right. So what is low slope is given by y tu minus violence divided by extra minus. Excellent. Right. So by two minus five and comes out to be one minus 0.5 divided by extra minus. Excellent, that is 3.4 minus 1.6. Okay, so slopes comes out to be 0.278 part on. Okay, because one by slope is resistance dimension of slope will be param. Okay, that means the resistance Resistance of the circuit would be equal to one divided by 0.278. That is 3.6 on. Okay, so that this is the resistance of this circuit. Thank you.
Hi french in the given circuit even and you too Is of three world he trees to hold. We have to find the value of island and I took see the current distribution. This is high too. Here you will get Ivan do the naming of the loop. We see deep E. F. G. Applying doctor chops loops law. Fuck B C D E. B. You will get -30. I do The last three is called 20. So I will be Point of one MPP and in a loop A B yeah. G. A. You will get minus tree less too minus stand into are even bless three is called to zero. So Ivan is .2 M. Pierre. Hence option is correct. That's all. Thanks for watching it.
Hi in this given problem there is our typical looking circuit diagram which is having tree, two ohm resistors in cities. Then here this is one more to own resistor here. Also, this is also one more to one resistors. So all these five resistors are in cities then there is Another two resistor in parallel. Then with this parallel combination, this too old in series, again, this to home in series. Then here this is eight home and finally connected with the battery providing the potential of 24 volt. But here these two terminals are shown to be our to do. Hence as the circuit is art with eight ohm resistor. So actually there is only This eight Ohm resistor in circuit with the battery means the circuit effective circuit is like this. So the net current passing through this eight ohm resistor will be given by R. Is equal to be by are using home slaw. So this is 24 by eight means this is 3.0 MPR. Hence here we can say our option B. Yes correct here, thank you.
In this question, we have two resistors in series. Okay. One is 1.5 mega owns, and the other one is 2.5 mega owns. Okay? It's connected to a battery. And then we are given that this is six sports, So we're going to find a E. M. F. Of the battery and the current in the circuit. Okay. So to do part A. Okay, That's called this are one uh two K. R. One is 1.5. Make our own Tartu is 2.5 McAdam. Okay. So you know that occurrence the same in a series of kids. Okay. Which means that uh having is the same in serious against. Okay. Which means that I one equals to two. Okay. We one of our, one equals to two of our two. Okay? So to find uh the mm of the battery, we need to find me to first. Okay? So we two is equal to Our 2/1. Thanks everyone, and this is 2.5 By 1.5 times six. Okay. And the answer is 10 votes. So the M. F. Of the battery, Is he going to be one Class B 2? And You get uh six plus 10 equals two, 16. So the mm for the battery is 16 votes. And then next we want to find a second current. Okay, So the second current can be found using uh we want over our one key and this is six divided by 1.5 mega homes. The answer is 4.0 Microbe. NPR. Okay, so this is the answer for part B and that's all for this question.
