Question

A small signal voltage V(t) = V₀ sin wt is applied across an
ideal capacitor C : [2016]
(a) Current I (t), lags voltage V(t) by 90°.
(b) Over a full cycle the capacitor C does not consume
any energy from the voltage source.
(c) Current I (t) is in phase with voltage V(t).
(d) Current I (t) leads voltage V(t) by 180°.

Answer 1
