In the given circuit, P ≠ R, the reading of the galvanometer is same with switch S open or closed. Then –

A

IR = IG

B

IP = IG

C

IQ = IG

D

IQ = IR

Answer

IR = IG

Explanation

Solution

It is given that presence of switch in the circuit is meaningless. Since R and G now become in series, so, IR = IG
