How do capacitors discharge
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. WebStep 4 Touch the black, or negative, tip of the discharge pen to the capacitor's cathode. This is the lead that you previously identified with the minus symbol on the side of the capacitor. Touch the red, or positive, tip of the discharge pen to the other lead, the capacitor's anode.
