Current Question (ID: 17389)

Question:

$\text{In an electric circuit, there is a capacitor of reactance } 100 \, \Omega \text{ connected across the source of } 220 \, \text{V. The rms value of displacement current will be:}$

Options:

1. $2.2 \, \text{A}$
2. $0.22 \, \text{A}$
3. $4.2 \, \text{A}$
4. $2.4 \, \text{A}$

Solution:

$\text{Displacement current and conduction current are equal.}$ $\therefore \, I_D = \frac{E}{Z} = \frac{220}{100} = 2.2 \, \text{A}$
