Electrostatic Potential And Capacitance

Question
CBSEENPH12039366

How does Ampere-Maxwell law explain the flow of current through 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. 

Solution

During charging, electric flux between the plates of capacitor keeps on
changing; this results in the production of a displacement current
between the plates.
Expression for the displacement current
contour integral stack straight B space space with rightwards arrow on top. dl with rightwards arrow on top space equals space straight mu subscript 0 left parenthesis straight I subscript straight C space plus dφ subscript straight E over dt
