Review Questions If four resistors in a circuit are connected in series, which of the following is the same for the resistors in the circuit? a. potential difference across the resistors b. current in the resistors

High in the given problem here, this is a circuit diagram having a combination of various resistors. The 1st 1 is 2.0 home. Then here this is 1.0 home. Another 1.0 home in series with it. Then 240m resistors in parallel with each other, and then finally A 3.0 Own Resistor. Then across all of them, A 6.00m resistor and then a battery Providing a potential of 12.0 world. No, in the first part of the problem we have to find equivalent resistance between the terminals A and B. For which first of all these two foreign resistors are in a parallel combination so they're not. Resistance will be denoted by our service script. P. Then these 2 1 home resistors are in cities so you will represent their net combination S. R. S. So using the rule of parallel accommodation here, this RP will be given by 4.0 x 20 means this is 2.0. Oh and the serious combination. R. S. Is 1.0 plus 1.0 home Doans this is 2.0 home. No this R P and R. S are in parallel combination. So their net resistance may be represented as RP dash. That will be given by do one Seattle Divided by two. As we know when identical resistors are put in parallel combination. Then net Resistance of Peril combination is given by the value of one resistor divided by the number of resistors here. The two resistors, R P and R. S. Both are having 2.0 on and these are two in number. That's why this is one Point Seattle Home. Finally this RP dash complete. Yeah this is R P dash complete. This is in series with 2.0 and 3.0 home. So as RP dash 210 home and 3.0 homes are in series so they're not resistance which may be represented as R. S. Dash. He's given us 210 Plus 1.0 for our videsh plus 3.0 home Which comes out to be 6.000 and at last this whole complete 6.0 is in parallel with this 6.0 on. So finally we can right R. S dash is in parallel With 6.0 own. So net effective resistance between terminals A B is our A. B is equal to value. Often resistance in parallel divided by the number And these are two in numbers. So this is 3.0 home, which becomes the answer for the first part of this problem. Now, the second part of the problem, we have to find the potential drop taking place across each forum resistor for this purpose. First of all, we will find the current passing through this branch whose resistance is our B dash. Who's residences Rs dash so has potential for be part as potential remains the same in parallel. So the potential for the branch having met resistance our stash will be 12.0 World hands current passing through this branch I will be given as total potential applied divided by R. S. Dash. So this is 12.0 divided by six and it comes out to be 2.0 ampere. The current passing through this branch His 6.0 and yet now the currently being same in series so the current a cruise. This parallel combination will also be six and the earth and as current remains the scene in cities so current through that parallel combination means our videsh will also be six. Sorry, that is two ampere. So here also This is 2.0 ampere not 6.0 ampere. So this is to 10 M. Pierre. Hence potential drop taking place across this parallel combination. VP dash will be equal to I into our means I into RP dash. This is VP dash equals two. 2.0 multiplied by Rpgs, which is 1.0 on. So this is 2.0 world and as forum and forum are in parallel and potential remains scene in parallel hands. Potential across each forum resistor is 2.0 volt. Answer for the second part. Finally, in the third part we have to find the current passing through three armed resistor but As the current here through 2.0 arm is 2.0 ampere. So this current will remain same in serious combination. So the current here through three Ohm resistor is also two, NPR as current remains the same in series. So current through 3.00m resistor is also 2.0 Ampere, which becomes the answer for the last part of this problem. Thank you.

When the foresters character in the streets like this one. Obviously, they're not one thing that whether it is the same razor or not. So basically, you're not going to talk over there. So, first of all, whether the potential difference would be not same as long as the resistance is not same, so it would be present that will not crack ups. And so that's apparently a current will be sore, whether it is a different result on the same. So yeah, the current will be the same for the all.

So are equivalent will be 1/1 over six home plus one over to OEMs. Thus one over. That's three home and here we have 1/1 plus one. So there's two ohm plus one over foreign foreign parallel. So 1/4 home that's 1/4 home universal that equals three off now way will have the current equals. 12. Vote over three or equals four amp So the vultures that were looking for this 12 old miners yeah to amp drop across to on registered and to amp drop across three on registered So voltage comes out to be two volt on current through the three on Registered is a do.

Hello and welcome to Chapter 18 Problem number 12 in Holt Physics. So this problem is really trying to get a familiar with the ah, the first steps of asking if resistors in parallel or resistors in Siris. So this question is asking, What are this? What's the same between any? A set of four resistors here that I have drawn in parallel. We have four resistors in parallel is asking if the current is the same I or the voltage is the same V. Um And so really, the short answer is that it's voltage. Any time you have voltage going, uh, components in parallel. The voltage is going to split right at the point here where the ah where they split and become parallel. So the vultures going to split evenly between each of these four resistors here, and so they all will share the same amount of potential difference
