A) the maximum voltage between plates is 220 V
B) the current is in phase with the applied voltage
C) the charge on the plate is not in phase with the applied voltage
D) power delivered to the capacitor per cycle is zero
Correct Answer: D
Solution :
(d) power delivered to the capacitor per cycle is zero When AC voltage of 220 V is applied to a capacitor C the charge on the plates is in phase with the applied voltage. As the circuit is pure capacitive so, the current developed leads the applied voltage by a phase angle of \[90{}^\circ \]. Hence, power delivered to the capacitor per cycle is \[P={{V}_{rms}}{{l}_{rms}}\cos \,90{}^\circ =0\]
