# Alternating currents - Phase angle, current, capacitance, and voltage

A coil is connected to a 60 Hz, 100-v ac generator. At this frequency, the coil has an impedance of 10 omega and a reactance of 8 omega. (a) What is the current of the coil? (b) What is the phase angle between the current and the applied voltage? The current and voltage so that current and voltage are in phase? (c) What series capacitance is required so that the current and voltage are in phase? (d) What is the voltage measured across the capacitor?
