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 2, CD is a non-reactive resistor of 833 in series with a standard capacitor of 0.38 F, and DA is a non-reactive resistor of 16800 2. If the supply frequency is 50 Hz, determine the inductance and the resistance at the balance condition. Created by Dr. A. R. C1 in m as D ww 16800 12 D RA 50Hz 100012 www 0.38 F 883 (2
