    Undergrad Where Does the Extra Energy in a Capacitor Come From?

    A capacitor is connected to a battery. If a person pulls the plate to increase the distance by 2d the decrease in energy between the plates is E. We observe energy gained by battery is 2E. From where does extra energy E come from.?
