electrophorus Quick reference
A Dictionary of Electronics and Electrical Engineering (5 ed.)
... 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....

A Dictionary of Psychology (4 ed.)
...organ n. A specialized area of modified muscle tissue in certain fishes such as the electric eel ( Electrophorus electricus ), the electric catfish ( Malapterurus electricus ), or the electric ray ( Tetranarce occidentalis ), such tissue being capable of discharging an electric shock to any animal that touches it. See also electroreceptor...

...Volta, Alessandro Giuseppe Antonio Anastasio ( 1745–1827 ) Italian physicist . In 1774 he began teaching in Como and in that year invented the electrophorus . He moved to Pavia University in 1778 . In 1800 he announced his invention of the voltaic cell , thus providing the first practical source of electric current ( see also Galvani, Luigi ). The SI unit of potential difference is named after...
electric organ Quick reference
A Dictionary of Biology (8 ed.)
...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...

In 1800 he made the first voltaic cell , thus providing the first practical source of electric current. The invention of the voltaic cell very soon led to the discovery of electrolysis , thus demonstrating a close link between chemistry and electricity. The SI unit of potential difference is named after...
