... An early form of simple electrostatic charge generator. A flat dielectric plate (‘cake’) is positively charged by friction. A metal plate with an insulated handle is placed on the cake and momentarily earthed, taking with it an induced negative charge when it is removed. The process can be repeated until the original positive charge has leaked away. ...

...electrophorus An early form of electrostatic generator . It consists of a flat dielectric plate and a metal plate with an insulated handle. The dielectric plate is charged by friction and the metal plate is placed on it and momentarily earthed, which leaves the metal plate with an induced charge of opposite polarity to that of the dielectric plate. The process can be repeated until all of the original charge has leaked away....

...electric organ An organ occurring on the body or tail of certain fish, such as the electric ray ( Torpedo ) and electric eel ( Electrophorus electricus ). It gives an electric shock when touched and is used either to stun prey or predators or, in some species, to maintain a weak electric field in the surrounding water that is used in navigation. The organ is composed of modified muscle cells ( electroplate or electroplax cells ), nervous stimulation of which greatly increases the potential difference across the cell. The electroplates are in series so a high...
