When an a.c. voltage is applied to a capacitor, no power is consumed because the current
leads the voltage by 90°
lags behind the voltage by 90°
and voltage are in phase
and voltage are 180° out of phase
Explicação
In a capacitive circuit, current leads voltage by 90°, or voltage lags current by 90°
