How does a capacitor work?

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.

Is a capacitor a battery?

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.

What is a capacitor in Electrical Engineering?

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.

Why do capacitors have two plates?

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.

How does a capacitor store energy?

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.

How much electricity can a capacitor store?

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.
