At balance, an a.c. bridge PQRS used to measure the inductance and resistance of an inductor has the following values: PQ-a non-inductive 4000 resistor; QR-the inductor with unknown inductance Lx in series with resistance Rx; RS-a 3 uF capacitor in series with a non-inductive 2500 resistor, SP-a 15 pF capacitor. A detector is connected between Q and S and the a.c. supply is connected between P and R. Derive the balance equations for Rx and Lx and determine their values.
