How does Ampere- Maxwell law expalain the flox of current trough a capacitor when it is being charged by a battery? Write the expression for the displacement current in terms of the rate of change of electric flux.

Text Solution

Verified by Experts

During charging, electric flux between the plates capacitor keeps on changing. This results in the production of displacement current between the plates.
