Question:

What is the rate of change of electric flux through the space between the plates of a capacitor given by?

(id is the displacement current)

Options:

id /2εο

id /2πεο

id /πεο

id /εο

Correct Answer:

id /εο

Explanation:

The expression for the displacement current : id = εο [dΦ/dt]

$\Rightarrow \frac{d\phi}{dt} = \frac{i_d}{\epsilon_0}$
