Question

The four arms of  a  bridge at balance are: arm ab, an unknown   impedance; arm bc, a  resistance  of 100 Ω; arm cd, a capacitor of 0.4 µF in series with resistance of 500 Ω;  arm da, a resistance of  300 Ω. If the supply frequency is 50Hz, determine the value of unknown impedance.
​

Answer 1

Answer:

a resistance of 100 Ω; arm cd, a capacitor of 0.4 µF in series with resistance of 500 Ω;

arm da, a resistance of 300 Ω. If the supply frequency is 50Hz, determine the value of
