Question:

An alternator supplies a peak current of 4.68 A to a coil with a negligibly small internal resistance. The voltage of the alternator is 420-V peak at 60.0 Hz. When a capacitor of 38.0 μ F is placed in series with the coil, the power factor is found to be 1.00. Find
(a) The inductive reactance of the coil and
(b) The inductance of the coil.
