Electromagnetic Waves

A capacitor of capacitance $C$ is connected across an ac source of voltage $V$ , given by $V = V_{0} sin ω t$ . The displacement current between the plates of the capacitor would then be given by:

A. $I_{d} = V_{0} ω C cos ω t$ ✓
B. $I_{d} = \frac{V _{0}}{ω C} cos ω t$
C. $I_{d} = \frac{V _{0}}{ω C} sin ω t$
D. $I_{d} = V_{0} ω C sin ω t$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
