☞ See the Note under Galvanism. [ 1913 Webster ]

Voltaic arc, a luminous arc, of intense brilliancy, formed between carbon points as electrodes by the passage of a powerful voltaic current. --
Voltaic battery, an apparatus variously constructed, consisting of a series of plates or pieces of dissimilar metals, as copper and zinc, arranged in pairs, and subjected to the action of a saline or acid solution, by which a current of electricity is generated whenever the two poles, or ends of the series, are connected by a conductor; a galvanic battery. See Battery, 4. (b), and Note. --
Voltaic circuit. See under Circuit. --
Voltaic couple or
Voltaic element, a single pair of the connected plates of a battery. --

n. [ Cf. F. voltaïsme. ] (Physics) That form of electricity which is developed by the chemical action between metals and different liquids; voltaic electricity; also, the science which treats of this form of electricity; -- called also galvanism, from Galvani, on account of his experiments showing the remarkable influence of this agent on animals.
