Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.

What happens when a capacitor discharges?

As more charge is stored on the capacitor, so the gradient (and therefore the current) drops, until the capacitor is fully charged and the gradient is zero. As the capacitor discharges (Figure 3 (b)), the amount of charge is initially at a maximum, as is the gradient (or current). The amount of charge then drops, as does the gradient of the graph.
