When an a.c. voltage is applied to a capacitor, no power is consumed because the current
-
A.
leads the voltage by 90° -
B.
lags behind the voltage by 90° -
C.
and voltage are in phase -
D.
and voltage are 180° out of phase
Correct Answer: Option A
Explanation
In a capacitive circuit, current leads voltage by 90°, or voltage lags current by 90°
