A small signal voltage V(t) = V0 sin$\omega $t is applied across an ideal capacitor C

Question

A small signal voltage V(t) = V₀ sin$\omega $t is applied across an ideal capacitor C

Current $I(t)$ is in phase with voltage $V(t)$.

Current $I(t)$ leads voltage V(t) by 180^o

Current $I(t)$, legs voltage $V(t)$ by 90^o.

Over a full cycle the capacitor C foes not consume any energy from the voltage source.
