Capacitors - Technical MCQs

Q1:

In a purely capacitive circuit,

A current leads voltage by 90°

B voltage leads current by 90°

C current lags voltage by 90°

D current and voltage have a phase relationship of 0°

ANS:A - current leads voltage by 90°

In pure capacitors current Waveform starts before voltage Waveform by a 90 degree difference so current leads voltage by 90 degree option(A) is the correct.
