A small signal voltage $V(t) = V_0\,\, sin \omega \,t$ is applied across an ideal capacitor $C$

  • [NEET 2016]
  • A

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

  • B

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

  • C

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

  • D

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