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 coupleor element, a single pair of the connected plates of a battery.Voltaic electricity. See the Note under Electricity.Voltaic pile, a kind of voltaic battery consisting of alternate disks of dissimilar metals, separated by moistened cloth or paper. See 5th Pile.Voltaic protection of metals, the protection of a metal exposed to the corrosive action of sea water, saline or acid liquids, or the like, by associating it with a metal which is positive to it, as when iron is galvanized, or coated with zinc.

(Vol*tair"e*an) a. [Cf. F. voltairien.] Of or relating to Voltaire, the French author. J. Morley.

(Vol*tair"ism) n. The theories or practice of Voltaire. J. Morley.

(Vol"ta*ism) 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.

(Vol*tam"e*ter) n. [Voltaic + - meter.] (Physics) An instrument for measuring the voltaic electricity passing through it, by its effect in decomposing water or some other chemical compound acting as an electrolyte.

(Vol"ta*plast) n. [Voltaic + Gr. molded.] A form of voltaic, or galvanic, battery suitable for use electrotyping. G. Francis.

(||Vol"ta) n.; pl. Volte [It. volta a turn, turning, a time. See Volt a tread.] (Mus.) A turning; a time; — chiefly used in phrases signifying that the part is to be repeated one, two, or more times; as, una volta, once. Seconda volta, second time, points to certain modifications in the close of a repeated strain.

(Vol"ta-e*lec"tric) a. Of or pertaining to voltaic electricity, or voltaism.

(Vol`ta-e`lec*trom"e*ter) n. An instrument for the exact measurement of electric currents.

(Vol"tage) n. (Elec.) Electric potential or potential difference, expressed in volts.

(Vol*tag"ra*phy) n. [Voltaic + - graphy.] In electrotypy, the act or art of copying, in metals deposited by electrolytic action, a form or pattern which is made the negative electrode. [R.]

(Vol*ta"ic) a. [Cf. F. voltaïque, It. voltaico.]

1. Of or pertaining to Alessandro Volta, who first devised apparatus for developing electric currents by chemical action, and established this branch of electric science; discovered by Volta; as, voltaic electricity.

2. Of or pertaining to voltaism, or voltaic electricity; as, voltaic induction; the voltaic arc.
