A capacitor stores electric charge. It’s a little bit like a battery except it stores energy in a different way. It can’t store as much energy, although it can charge and release its energy much faster. This is very useful and that’s why you’ll find capacitors used in almost every circuit board. How does a capacitor work?
By themselves, capacitors are often used to store electrical energy and release it when needed; with other circuit components, capacitors often act as part of a filter that allows some electrical signals to pass while blocking others. You can see why capacitors are considered one of the fundamental components of electrical circuits.
MagLab: Capacitor Tutorial: An interactive Java page that allows you to experiment with using capacitors in a simple motor circuit. You can see from this how a capacitor differs from a battery: while a battery makes electrical energy from stored chemicals, a capacitor simply stores electrical energy for a limited time (it doesn't make any energy).
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.
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.
The foil sheets are connected to terminals (blue) on the top so the capacitor can be wired into a circuit.

You can charge a capacitor simply by wiring it up into an electric circuit.
