    • n electrophorus Pl. electrophori (-rī). An instrument for obtaining statical electricity by means of induction. It consists of a disk of resin, or other non-conducting material easily excited by friction, and a polished metal disk with an insulating handle. The resin disk is negatively electrified by striking or rubbing it with a catskin or flannel, and the metal plate is then laid upon it. Under these circumstances the upper plate does not receive a direct charge from the lower, but is positively charged on the lower surface and negatively on the upper; if now the disk is touched by the finger, the negative electricity passes to the ground, leaving the disk charged positively. On being lifted away by its insulating handle, it is found to be charged, and will give a spark. It may then be replaced on the lower plate, and the process repeated an indefinite number of times without any fresh excitation, if the weather is favorable. The electricity obtained each time is the equivalent of the mechanical work done in separating the two surfaces against the attraction of the unlike electricities.
    • n electrophorus [capitalized] The typical genus of Electrophoridæ. There is but one species, the electric eel, E. electricus. Gill, 1864. See cut under eel.
