Physics A level revision resource: Introduction to capacitors
Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.The voltage V is proportional to the amount of charge which is already on …
batteries
The ultracap, however, will drop from 3V to 2V and still have almost half the total charged energy still in the capacitor, unavailable to us because of the drop-out voltage of the phone. So not only is the total energy density of the capacitor much lower than that of the battery, we can''t even use all the energy that''s there.
