When an AC voltage of 220 V is applied to the capacitor C (a) the maximum voltage between plates is 220 V. (b) the current is in phase with the applied voltage. (c) the charge on the plates is in phase with the applied voltage. (d) power delivered to the capacitor is zero.
Correct options are C) and D) When an 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∘ Hence , power delivered to the capacitor per cycle is P=VrmsIrmscos90∘=0
