In the circuit `P != R, ` the reading of the galvanometer is same with switch S open or closed. Then

A

`I_(R)=I_(G)`

B

`I_(P)=I_(G)`

C

`I_(Q)=I_(G)`

D

`I_(Q)=I_(R)`

Text Solution

Verified by Experts

The correct Answer is:
A
As there is no change in the reading of galvanometer with switch S open or closed. It implies that bridge is balanced current through S is zero and `I_(R)=I_(G),I_(P)=I_(Q)`
