A small signal voltage $V (t) = V_{0} \sin ω t$ is applied across an ideal capacitor $C$ :NEET 2016 (Phase 1)

Answer:

Solution:

In capacitor current leads the voltage by $ϕ = \frac{π}{2}$ phase. Average power dissipated in AC circuit is given by

$P_{a v} = V_{r m s} I_{r m s} \cos (ϕ)$

In capacitor $ϕ = \frac{π}{2}$ so $\cos (\frac{π}{2})$ is zero.
