In the given potentiometer circuit length of the wire `AB` is `3 m` and resistance is `R = 4.5 Omega`. The length `AC` for no deflection in galvanometer is

A

`2m`

B

`1.8 m`

C

dependent on `r_(1)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
Since cell connected in secondary circuit is in wrong way so we will not get balancing point.
