A capacitor (formerly known as a "condenser") is a device that stores electric charge, or, more accurately, consists of two plates which each store an opposite charge. These two plates are conductive and separated by an insulator or dielectric. The charge is stored on the inside of the plates, at the boundary with the dielectric.

Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work.

A type of capacitor in which one plate is coated through electrolysis with an oxide to serve as the dielectric, while the other plate is replaced by an electrolyte. Electrolytic capacitors can achieve very high capacitance with very small sizes, but only act as capacitors as long as the current flows in one direction.

The maximum energy that can be (safely) stored in a particular capacitor is limited by the maximum electric field that the dielectric can withstand before it breaks down. Therefore, capacitors made with the same dielectric have about the same maximum energy density (joules of energy per cubic meter), if the dielectric volume dominates the total volume.

In a capacitor electrical energy is stored by a difference in charge between two metal surfaces. The amount of energy that a capacitor can store depends on the insulating material in between the metal surfaces, called a dielectric.

The capacitor or the electrical condenseris a device for storing an electrical charge. In its simplest form a capacitor consists of two metal plates separated by a nonconducting layer called the dielectric.
