- The Wheatstone bridge works on the principle of null deflection, meaning the ratio of their resistances are equal and no current flows through the circuit. The formula used for Wheatstone bridge is, R = PS/Q, Where, R is the unknown resistance, S is the standard arm of the bridge, P and Q is the ratio of the arm of bridge.
