NEET Physics Current Electricity Questions Solved

In the circuit shown PR, the reading of the galvanometer is same with switch S open or closed. Then 

(1) IR=IG

(2) IP=IG

(3) IQ=IG

(4) IQ=IR

(1) Reading of galvanometer remains same whether switch S is open or closed, hence no current will flow through the switch i.e. R and G will be in series and same current will flow through them IR=IG
