Q3) THREE identical coils each having inductance 0.1 H and resistance 30 Ω are connected in delta to a three-phase, 440 V, 50 Hz supply. THRRE identical capacitors, arranged in star, are connected in parallel with the delta load to raise the power factor to 0.9 lagging.

Calculate EACH of the following:

(a) the value of each capacitor; (12)

(b) the percentage reduction in line current. (4)
