WebOct 27, 2024 · Capacitors discharge to send their charges to ground, or to get zero electric potential. Because all charges whether they are positive or negative have the tendency to flow the ground so as you provide them a path to flow to ground or zero electric potential they will flow to the zero potential to minimize their electric potential energy. WebWhen a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the …
