An alternating voltage of amplitude $40\ \text{V}$ and frequency $4\ \text{kHz}$ is applied directly across a capacitor of $12\ \mu\text{F}$. The maximum displacement current between the plates of the capacitor is nearly
Answer: (B) $12\ \text{A}$
The displacement current equals the conduction current:
$$I_0 = V_0\,\omega C = 40\times2\pi\times4000\times12\times10^{-6} \approx 12\ \text{A}$$
