An rms voltage of 20.5 V with a frequency of 1.00 kHz is applied to a 0.395-F

Question:

An rms voltage of 20.5 V with a frequency of 1.00 kHz is applied to a 0.395-μF capacitor.
(a) What is the rms current in this circuit?
(b) By what factor does the current change if the frequency of the voltage is doubled?
(c) Calculate the current for a frequency of 2.00 kHz.
