The charge on a parallel plate capacitor varies as q = q_o cos 2\(\pi \gamma \)t. The plates are very large and close together. (area - A. separation - d) find the displacement current through the capacitor?

A variable frequency ac source is connected to capacitor. How will the displacement current change with decrease in frequency.

How does Ampere - Maxwell law expalain the flux 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.
