Question

when an ac voltage of 220V is applied to the capacitor C than_____​

Answer 1

When an a.c. voltages of 220 V is applied to a capacitor C, the charge on the plates is in phase with the applied voltage. As current developed leads the applied voltage by a phase angle of 90∘, therefore, power delivered to the capacitor per cycle is P=EυIυcos90∘ = zero. Choices (c) and (d) are correct.
