At some instant, we connect it across a battery, giving it a potential difference (V = q/C) between its plates. Initially, the charge on the plates is (Q = 0). As the capacitor is being charged, the charge gradually builds up on its plates, and after some time, it reaches the value Q.

Electrical current can not actually flow through a capacitor as it does a resistor or inductor due to the insulating properties of the dielectric material between the two plates. However, the charging and discharging of the two plates gives the effect that current is flowing.

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its

A capacitor is formed of two square plates, each of dimensions (a times a), separation (d), connected to a battery. There is a dielectric medium of permittivity (epsilon) between the plates. I pull the dielectric medium out at speed (dot x). Calculate the current in the circuit as the battery is recharged. Solution.
