An AC generator with an output rms voltage of 42 V at a frequency of 60 Hz is connected across a 9 µF capacitor. Find the following.

(a) capacitive reactance

(b) rms current

A

(c) maximum current in the circuit

3 A

(d) When does the capacitor have its maximum charge?

4

1/3 cycle before the voltage reaches its maximum value1/2 cycle before the voltage reaches its maximum value1/4 cycle before the voltage reaches its maximum valuethe capacitor's charge is uniform when the current takes its maximum value
