As soon as power source is turned off, capacitor starts to discharge through the resistor. Discharge resistor can be externally connected or mounted inside the capacitor can. Downside of using permanently connected external or internal resistor is steady state power loss.
When a charged capacitor is connected to a resistor, the charge flows out of the capacitor and the rate of loss of charge on the capacitor as the charge flows through the resistor is proportional to the voltage, and thus to the total charge present. so that is the initial charge on the capacitor (at time t = 0).
Easiest and most reliable way to ensure capacitor discharge is to permanently connect resistors across the capacitor terminals. As soon as power source is turned off, capacitor starts to discharge through the resistor. Discharge resistor can be externally connected or mounted inside the capacitor can.
It’s essentially a high-value resistor connected across the terminals of a capacitor or between the positive and negative voltage rails in a power supply circuit. This tool calculates the value of Resistance (Ω) required to discharge a capacitor in a specified amount of time.
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 rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge.

The purpose of a resistor connected across a capacitor, known as a discharge resistor, is to facilitate the safe and controlled dissipation of stored charge when the capacitor is no longer needed to maintain a voltage or store energy.
The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge. It ...
