Standard Books Physics AC Circuits MCQ Question with Solution

A parallel plate condenser of capacity 100 pF is connected to 230 V of AC supply of 300 rad s⁻¹ frequency. The rms value of displacement current.

A

6.9 μA

B

2.3 μA

C

9.2 μA

D

4.6 μA

Correct Answer

Option A

Detailed Explanation

Using the formula $I_{rms} = E_{rms} \times X_c \times \omega C$ , where $X_c = \frac{1}{\omega C}$ , the calculation gives 6.9 μA.
