coil of resistance 12 Ω and inductance 0.4 H is connected in parallel with a non-inductive
resistance of 15 Ω. Find the
(i) current in each branch of the circuit,
(ii) total current supplied,
(iii) phase angle and power factor of the combination when a voltage of 220 V at 50 Hz is
applied and
(iv) power consumed in the circuit.
