A capacitor of 8.0 μF takes a current of 1.0

A capacitor of 8.0 μF takes a current of 1.0 A when the alternating

voltage applied across it is 230 V. Calculate:

(a) the frequency of the applied voltage;

(b) the resistance to be connected in series with the capacitor to

reduce the current in the circuit to 0.5 A at the same frequency;

(c) the phase angle of the resulting circuit
