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