A capacitor (originally known as condenser) is a passive two-terminal electrical component used to store energy in an electric field. The forms of practical industrial capacitors vary widely, but all contain at least two electrical conductors separated by a dielectric (insulator); The capacitance is greatest when there is a narrow separation between large areas of conductor, hence capacitor conductors are often called plates, referring to an early means of construction. In practice, the dielectric between the plates passes a small amount of leakage current and also has an electric field strength limit, resulting in a breakdown voltage, while the conductors and leads introduce an undesired inductance and resistance. Most types of industrial capacitors include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them. AMELT filter and tank capacitors are equipped with internal discharging resistors as well as a pressure switch in case of body deformation and short circuits.
