Time :
1. A small signal voltage V (t) = V
0
sinωt is applied across an ideal capacitor C
(1). Current /(f) is in phase with voltage V(t).
(2). Current /(f) leads voltage V(t) by 180°.
(3). Current /(f), lags voltage V(t) by 90°
(4). Over a full cycle the capacitor C does not consume any energy from the voltage source
