The two ends of a uniform conductor are ...

The two ends of a uniform conductor are joined to a cell of e.m.f. `E` and some internal resistance. Starting from the midpoint `P` of the conductor, we move in the direction of current and return to `P`. The potential `V` at every point on the path is plotted against the distance covered `(x)`. which of the following graphs best represent the resulting curve ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
