Two resistors 10 Ω and 5 Ω are connected in parallel across a 15 V battery. What is the potential difference across the 10 Ω resistor?

I got 45 V because R=3.33 Ohms so I=4.5 A and change in velocity = 4.5*10 = 45V, but the choices are
5V
10V,
15V,
and 20V.
So what am I doing wrong?

Isn't the voltage equal for all paths when they are in parallel?

anonymous · Answer

I think so, yes.

So I think you have |dw:1392953314960:dw|
If the voltage is equal on both paths then it would just be 15 V across both resisters?
