A small signal voltage$\mathrm{V}\left(\mathrm{t}\right)={\mathrm{V}}_0 \sin \mathrm{\omega t}$ is applied across an ideal capacitor C

• A

  $\text{ Current }I\left(t\right)\text{ is in phase with voltage }V\left(t\right)$

• B

  $\text{ Current }I\left(t\right)\text{ leads voltage }V\left(t\right)\text{ by }180°.$

• C

  $\text{ Current }I\left(t\right)\text{ , lags voltage }V\left(t\right)\text{ by }90°\text{ . }$

• D

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