Inside a Capacitor. Inside a basic capacitor, there are two metal plates, usually made of aluminum. These plates are separated by a special insulating material called a dielectric, which can be made of ceramic. The dielectric material helps the capacitor store energy by polarizing when it encounters an electric field. Why Capacitors Matter

What is the capacitance of a parallel plate capacitor with metal plates, each of area (1.00 mathrm{m^{2}}), separated by 1.00 mm? The dielectric reduces the electric field strength inside the capacitor, resulting in a smaller voltage between the plates for the same charge. The capacitor stores the same charge for a smaller voltage

Learn MoreThe conductive plates of a capacitor are generally made of a metal foil or a metal film allowing for the flow of electrons and charge, but the dielectric material used is always an insulator. The various insulating materials used as the dielectric in a capacitor differ in their ability to block or pass an electrical charge.
Electrolytic capacitors are normally made from one of three different materials: aluminum, tantalum, and niobium. Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons:
However, for practical applications, specific materials are used that best suit the capacitor's function. Mica, ceramic, cellulose, porcelain, Mylar, Teflon and even air are some of the non-conductive materials used. The dielectric dictates what kind of capacitor it is and for what it is best suited.
Capacitors come in all shapes and sizes, but they usually have the same basic components. There are the two conductors (known as plates, largely for historic reasons) and there's the insulator in between them (called the dielectric).
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.
Aluminum is one of three metals manufacturers use for electrolytic capacitors for several reasons: - Aluminum acts as a so-called “valve” metal, where a positive voltage in an electrolytic bath allows it to form a thin oxide layer that acts as a dielectric. -The aluminum anode is made from pure aluminum foil, which can form many capacitive layers.
