In the circuit `PneR`, 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

Since opening or closing the switch does not affect the current through G, it means that in both the cases there is no current passing through S. This means that potential at A is equal to potential at B and it is the case of balanced Wheatstone bridge.
`I_p=I_Q I_R=I_G` and (a) is the correct option.
