The four arms of a Hay’s a.c. bridge are arranged as follows: AB is a coil of unknown impedance; BC is a non-reactive resistor of 1000 Ω ; CD is a non-reactive resistor of 833 Ω in series with a standard capacitor of 0.38 μF ; DA is a non-reactive resistor of 16,800 Ω . If the supply frequency is 50 Hz, determine the inductance and the resistance at the balance condition
