WebSPEAKER 1: Where does this 1/2 come from? How come the energy is not just Q times V? Well, the energy of a capacitor would be Q times V if during discharge, all of the charges were to drop through the total initial voltage, V. But during discharge, all of the charges won't drop through the total voltage, V. 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. alchimi deauville
