Question 33 of 165
An alternating voltage of amplitude and frequency is applied directly across the capacitor of . The maximum displacement current between the plates of the capacitor is nearly :
Show answer and solution
Answer: (B)
Displacement current is same as conduction current in capacitor.
$\begin{aligned}
& X_C=\frac{1}{\omega \mathrm{C}}=\frac{1}{2 \pi \mathrm{fC}} \\
& =\frac{1}{2 \pi \times 4 \times 10^3 \times 12 \times 10^{-6}}=3.317 \Omega
