A cell of itnernal resitance `1.5 Omega` and of e.m.f. `1.5` volt balances `500 cm` on a potentiomter wire. If a wirr of 15 `Omega` is connected between the balance point and the cell, then tha balance point will shift

A

To zero

B

By `500 cm`

C

By `750 cm`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Balance point has some fixed position on potentiometer wire. It is not affect by the additions of resistance between balance point and cell.
