8.4: Energy Stored in a Capacitor
As the capacitor is being charged, the charge gradually builds up on its plates, and after some time, it reaches the value Q. To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq).
