Capacitor Discharging Circuit
Section 37.1 Capacitor Discharging Circuit. A charged capacitor provides a ready supply of separated charges. When you provide a conducting path for excess electrons on the negative plate to drift to positive plate, it leads to discharge of the capacitor. This process releases electrical energy in a short time.

21.6: DC Circuits Containing Resistors and Capacitors
A small resistance (R) allows the capacitor to discharge in a small time, since the current is larger. Similarly, a small capacitance requires less time to discharge, since less charge is stored. In the first time interval (tau = RC) after the switch is closed, the voltage falls to 0.368 of its initial value, since (V = V_0 cdot e^{-1 ...

How to Safely Discharge a Capacitor?
The best way to select a proper resistor is to use this formula: P = V²/R, where P is the power in watts, V is the voltage across the resistor, and R is the resistance in ohms.. For example, let''s say you''re discharging a capacitor with a voltage of 25V. If you wanted to use a 100ohm resistor, then you would need a power rating of at least 0.25W (25V/100ohms = 0.25).
