Charging and discharging a capacitor from a d.c. source

WebTo discharge a capacitor, the two leads of the capacitor must be connected together so that there is a path for the current to drain through so the capacitor becomes depleted of its power. The quickest way to discharge a capacitor is to touch the two terminals of the capacitor together, as is shown below. WebThe time it takes for a capacitor to discharge is 5T, where T is the time constant. There is a need for a resistor in the circuit in order to calculate the time it takes for a capacitor to discharge, as it will discharge very quickly when there is no resistance in the circuit. In DC circuits, there are two states when a capacitor is discharging. http://www.coilgun.info/theorycapacitors/capacitorcharging.htm knowa island
