Question: an inductive coil when connected across 500 v 50 hz...

Question details

An inductive coil when connected across 500 V, 50 Hz supply draws 1.0 A at 0.8 pf. What capacitance is connected in parallel with the coil to make the power factor of the combination unity? What will be the current (i) drawn from the supply; and (ii) in each branch with this new capacitor. [Ans. 3.82 H F: (i) 0.8 A (ii) 1.0 A, 0.6 A]
