Explainer: How batteries and capacitors differ
When a picture is taken, that capacitor releases its energy quickly. Then, the capacitor begins to charge up again. Since capacitors store their energy as an electric field rather than in chemicals that undergo reactions, they can be recharged over and over again. They don''t lose the capacity to hold a charge as batteries tend to do.

6.1.2: Capacitance and Capacitors
Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}. Modest surface mount capacitors can be quite small while the power supply filter capacitors commonly used in consumer ...
Capacitor
As the capacity of a capacitor decreases the voltage drop increases. It resists the current flow as it is charged up. The more water stretching the membrane, the harder it is to stretch further. The higher the capacitance leads to a higher capacity. A stretchier membrane allows for more water before it is done stretching.

Are capacity and capacitance the same?
If by "capacity" you mean the amount of net charge on the plates, then obviously that''s not the same as the capacitance of the capacitor which is the charge divided by the voltage. The capacitance of a capacitor is greater if the work required per unit charge to separate the charge on the plates (i.e., the voltage) is less. Hope this helps.

Capacitor and Capacitance
Capacitors function a lot like rechargeable batteries. The main difference between a capacitor and a battery lies in the technique they employ to store energy. Unlike batteries, the capacitor''s ability to store energy doesn''t come from chemical reactions but from the physical design that allows it to hold negative and positive charges apart.

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
