For the genus of fish family Electrophoridae, see Electrophorus (fish).
Electrophorus from the 1800s.
In electromagnetism, an electrophorus or electrophore is a simple, manual, capacitive, electrostatic generator used to produce charge via the process of electrostatic induction. A first version of it was invented in 1762 by Swedish professor Johan Carl Wilcke.[1][2][3][4] Italian scientist Alessandro Volta improved and popularized the device in 1775,[5] and is sometimes erroneously credited with its invention.[6][7] The word electrophorus was coined by Volta from the Greek ήλεκτρον, elektron, and φορεύς, phoreus, meaning 'electricity bearer'.[8]
