11. DISCHARGING A CAPACITOR At first, it is easy to remove charge in the capacitor. Coulombic repulsion from charge already on the plates creates a force that pushes some of the charge out of the capacitor once the force (voltage) that placed the charge in the capacitor is removed (or decreased). As more charge is removed from the plates of the …

At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge decreases is proportional to the amount of current, p.d or charge it has left
