Capacitors provide temporary storage of energy in circuits and can be made to release it when required. The property of a capacitor that characterises its ability to store energy is called its capacitance. When energy is stored in a capacitor, an electric field exists within the capacitor.
Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.

Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
The Capacitor Discharge Equation is an equation which calculates the voltage which a capacitor discharges to after a certain time period has elapsed. Below is the Capacitor Discharge Equation: Below is a typical circuit for discharging a capacitor.
After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, a capacitor discharges 98.12% of the supply voltage. After 5 time constants, the capacitor discharges 99.3% of the supply voltage.
Resistors are the preferred discharge device for capacitors though reactors and voltage transformers can also be used if faster discharge is necessary. By using resistor, the rate of discharge, resistor power dissipation can be controlled to a high degree by the designer.
