An ac generator which produces an rms voltage of 120 v at, Ask an Expert

Academics

An A.C. generator which produces an RMS voltage of 120 V at 60 Hz is connected to a 57 µF capacitor. There are no other elements in the circuit. How is the phase of the current through the capacitor related to the phase of the voltage?

a. They have the same phase.

b. The current leads the voltage by a quarter of a cycle.

c. The current lags behind the voltage by a quarter of a cycle.

d. The current leads the voltage by an amount which depends on the capacitance and the RMS voltage.

e. The current lags behind the voltage by an amount which depends on the capacitance and the RMS voltage.
