2. To plate, as with gold, silver, etc., by means of electricity. [ 1913 Webster ]

3. To restore to consciousness by galvanic action (as from a state of suspended animation); hence, to stimulate or excite to a factitious animation or activity. [ 1913 Webster ]

4. To coat, as iron, with zinc. See Galvanized iron. [ 1913 Webster ]

Galvanized iron, formerly, iron coated with zink by electrical deposition; now more commonly, iron coated with zink by plunging into a bath of melted zink, after its surface has been cleaned by friction with the aid of dilute acid. [ 1913 Webster ]

n. [ Galvanic + -graphy. ] 1. The art or process of depositing metals by electricity; electrotypy. [ 1913 Webster ]

2. A method of producing by means of electrotyping process (without etching) copperplates which can be printed from in the same manner as engraved plates. [ 1913 Webster ]

n. One who describes the phenomena of galvanism; a writer on galvanism. [ 1913 Webster ]

pos>n. [ Galvanic + -logy. ] A treatise on galvanism, or a description of its phenomena. [ 1913 Webster ]

n. [ Galvanic + -meter: cf. F. galvanomètre. ] (Elec.) An instrument or apparatus for measuring the intensity of an electric current, usually by the deflection of a magnetic needle. [ 1913 Webster ]

Differential galvanometer. See under Differental, a. --
Sine galvanometer,
Cosine galvanometer,
Tangent galvanometer (Elec.), a galvanometer in which the sine, cosine, or tangent respectively, of the angle through which the needle is deflected, is proportional to the strength of the current passed through the instrument. [ 1913 Webster ]

a. Of, pertaining to, or measured by, a galvanometer. [ 1913 Webster ]

n. The art or process of measuring the force of electric currents. [ 1913 Webster ]

a. [ Galvanic + -plastic. ] Of or pertaining to the art or process of electrotyping; employing, or produced by, the process of electolytic deposition; as, a galvano-plastic copy of a medal or the like. [ 1913 Webster ]

n. [ Cf. F. galanoplastie. ] The art or process of electrotypy. [ 1913 Webster ]

n. (Med.) Same as Electro-puncture. [ 1913 Webster ]
