Resistor Combination: Current and Potential Difference Calculation

[smaung]

Hello,

I have a tricky problem with resistors combination.

please check this url - http://www.disruptedstreets.com/physics.png

Can anybody help me with this?

Thanks

The Question is -

Calculate the Current at Point X and potential difference between points A and B.

 

[jablonsky27]

looks to me like R1, R2, R3 are in parallel and the pot. difference between A and B is that provided by the battery.

 

[smaung]

yes me too

but some said ... there is a short circuit. but i don't know where is it ... :( and that's why I'm confused.

What does "X" represent?

 

[smaung]

"X" is the current at that point. We need to find the current ( I ) at "X". AND potential difference ( V ) between "A" and "B".

 

[smaung]

Oh sorry I Forgot. The battery is 2V.

 

[Defennder]

I don't see any short-circuit. But in any case as jablonsky27 has noted, the three resistors are all in parallel. That should simplify the problem tremendously.

yea me too.. but.. there is another fault. the polarities of the battery is wrong .. positive is up and negative is down

can you please calculate the answers for me ?

Turn the paper over.

can you please calculate the answers for me ?

No.

Compute the total resistance, apply Ohms law.

ok thanks.
