Capacitors Explained, in this tutorial we look at how capacitors work, where capacitors are used, why capacitors are used, the different types. We look at capacitors in Power factor and full bridge rectifiers to convert AC to DC.

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.Inside, the terminals connect to two metal plates separated by a non-conducting substance.When activated, a capacitor quickly releases electricity in a tiny fraction of a second.
Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric.The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte.
The nonconducting dielectric acts to increase the capacitor’s charge capacity. Materials commonly used as dielectrics include glass, ceramic, plastic film, paper, mica, air, and oxide layers. Capacitors are widely used as parts of electrical circuits in many common electrical devices.//wikipedia
