N identical current sources each of emf E and internal resistance r are connected to form a closed loop as shown in figure. The potential difference between points A and B which divides the circuit into n and (N-n) units is

A

`NE`

B

`(N-n)E`

C

`nE`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
