A small signal voltage \( V(t) = V_0 \sin \omega t \) 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 \( 180^\circ \).
3. Current \( I(t) \) lags voltage \( V(t) \) by \( 90^\circ \).
4. Over a full cycle the capacitor \( C \) does not consume any energy from the voltage source.
