(a) Describe the measures to be taken and the effect on various outputs when running a 60Hz system on a 50Hz supply. (6)

(b) A series circuit consists of a capacitor of 50µF and a coil of inductance 1.5H and resistance 300 Ohms. Find the total impedance when working on a 50Hz Supply. Find whether the current leads or lags the voltage. (10)
