The CONDENSER , whose first experiments and, basically, the invention can be traced back to Alessandro Volte around the year 1780. It is an electrical component that has the ability to store the electrostatic energy associated with an electrostatic field. A capacitor generally consists of a pair of conductors (armatures or plates) separated by an insulator (dielectric). The charge is stored on the surface of the plates, on the edge in contact with the dielectric. It is usually indicated with “C” = Capacity (its effect) and its unit of measurement is the Farad.
