A coil is in series with a 20 µF capacitor across a 230-V , 50-Hz supply. The current taken by the circuit is 8 A and the power consumed is 200 W. Calculate the inductance of the coil if the power factor of the circuit is (a) leading and (b) lagging. Sketch a vector diagram for each condition and calculate the coil power factor in each case.
