Thus this amount of mechanical work, plus an equal amount of energy from the capacitor, has gone into recharging the battery. Expressed otherwise, the work done in separating the plates equals the work required to charge the battery minus the decrease in energy stored by the capacitor. Perhaps we have invented a battery charger (Figure (V.)19)!
In storing charge, capacitors also store potential energy, which is equal to the work (W) required to charge them. For a capacitor with plates holding charges of +q and -q, this can be calculated: (mathrm { W } _ { mathrm { stored } } = frac { mathrm { CV } ^ { 2 } } { 2 }). The above can be equated with the work required to charge the ...
