Q7. A single phase a.c. circuit comprises a coil of inductance 0.5 H and resistance 100 Ω in series with a capacitor ‘C’. It is connected to 120 V, 50 Hz and draws a current at a leading power factor. The volt drop across the coil is 150 V. Calculate EACH of the following:

(a) The current in the circuit;

(b) The value of the capacitor;

(c) The power factor of the circuit;

(d) The power dissipated in the circuit.
