Question:

Maxwell's displacement current is

Options:

due to flow of charges

due to changing gravitational field

due to changing electric field

times the rate of change of magnetic flux

Correct Answer:

due to changing electric field

Explanation:

The correct answer is Option (3) → due to changing electric field

Maxwell's displacement current is

The displacement current density is given by

$J_d = \varepsilon_0 \frac{dE}{dt}$

It arises when the electric field changes with time, even in regions where no conduction current exists.
