Question

derive the P/Q=R/S principle of wheatstone bridge​

Answer 1

Answer:

The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal and no current flows through the circuit. Under normal conditions, the bridge is in the unbalanced condition where current flows through the galvanometer.

Answer 2

Whichstone bridge works on the principle of null deflection,if the ratio of their resistance is an equal and close to the circuit.Under normal conditions,the bridge unbalance condition when current flows to the galvanometer
