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

How does capacitance affect the discharge process?

C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can't hold as much charge, and thus, the lower V C at the end.
