WebJun 13, 2024 · Most techs use a screwdriver to discharge a capacitor, but Bryan shows a way to make a capacitor discharge tool to satisfy the nerdiest or most safety-conscious tech. WebOct 27, 2024 · The reason the capacitor discharged was that the external circuit, a resistor in this case, 'draws' on the stored energy in the capacitor (a resistor never supplies energy but can only dissipate it). Capacitors discharge to send their charges to ground, or to get zero electric potential.
WebJan 6, 2015 · 3 Answers. Sorted by: 1. Once the reservoir capacitor voltage goes below 0.6V there's not much you can do, because any transistor you try to use to discharge it further will also be turned off. However you could discharge the capacitor in the time delay circuit before the reservoir capacitor goes below 0.6V.
