On halving the capacitance at constant voltage, we lost half the original charge Q. This ½ Q goes into the battery against the voltage V, so the battery is recharged with restored energy ½ QV. Only half that energy pumped into the battery comes from energy stores in the capacitor’s electric field: the...

Only half that energy pumped into the battery comes from energy stores in the capacitor’s electric field: the rest comes from work done dragging the plates apart. read less
