The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.)
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
Capacitors are good for applications that need a lot of energy in short bursts. The energy storage capacity of a battery or capacitor is measured in watt-hours. This is the number of watt hours a battery or capacitor can store. Usually, batteries have a higher watt-hour rating than capacitors.
Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.) Electric potential, as the name might suggest, can drive a flow of electrons. Such a flow is called an electric current.
Engineers choose to use a battery or capacitor based on the circuit they’re designing and what they want that item to do. They may even use a combination of batteries and capacitors. The devices are not totally interchangeable, however. Here’s why. Batteries come in many different sizes. Some of the tiniest power small devices like hearing aids.
When a capacitor is connected to a battery, the charge is developed on each side of the capacitor. Also, there will be a flow of current in the circuit for some time, and then it decreases to zero. Where is energy stored in the capacitor? The energy is stored in the space that is available in the capacitor plates.
