A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store electrical energy and release it very slowly through a circuit; sometimes (in the case of a quartz watch) it can take several years. A capacitor generally releases its energy much more rapidly—often in seconds or less.
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals.
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.
Its two plates hold opposite charges and the separation between them creates an electric field. That's why a capacitor stores energy. Artwork: Pulling positive and negative charges apart stores energy. This is the basic principle behind the capacitor.
Instead, it can store and release energy when needed. Inside a capacitor, there are two conducting metal plates, separated by an insulating material called a dielectric. The plates can be made of different metal alloys, such as aluminum or tantalum, depending on the type of capacitor.
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
