Q6. Three identical coils each of inductance 0.1 H and resistance 30Ω are connected in delta to a three phase three wire supply of 440 V 50 Hz. Three identical capacitors connected in star are now joined to the same supply to raise the overall power factor to 0.9 lag.

Calculate EACH of the following:

(a) The value of each capacitor;

(b) The percentage reduction in line current;

(c) The kVA taken by the capacitors.
