Question:

A parallel plate capacitor is charged to 60μC. Due to a radioactive source, the plate loss charge at the rate of 1.8 × 10−8 Cs−1 . The magnitude of displacement current is

Options:

1.8 × 10−8 Cs−1

3.6 × 10−8 Cs−1

4.1× 10−11 Cs−1

5.7× 10−12 Cs−1

Correct Answer:

1.8 × 10−8 Cs−1

Explanation:

Displacement current is given by

$I_d=\frac{dq}{dt}= 1.8×10^{-8} \,Cs^{-1}$
