The motion of electricity or its passage from one metal to another in a voltaic circuit; mechanical action produced by means of electricity.

relatively to some other associated body or bodies, as to tend to the negative pole of a voltaic battery, in electrolysis, while the associated body tends to the positive pole; - - the converse or correlative of electro-negative.

A style of engraving in relief by means of voltaic electricity. A picture is drawn on a metallic plate with some material which resists the fluids of a battery; so that, in electro-typing, the parts not covered by the varnish, etc., receive a deposition of metal, and produce the required copy in intaglio. A cast of thi…

trical currents by the mutual action of certain liquids and metals; -- now usually called voltaic battery. See Battery. -- Galvanic circuit or circle. (Elec.) See under Circuit. -- Galvanic pile (Elec.), the voltaic pile. See under Voltaic.

A process similar to etching, in which, by means of voltaic electricity, a raised copy of a drawing is made, so that it can be used to print from.

nd as a lubricator, etc. Often called plumbago or black lead. Graphite battery (Elec.), a voltaic battery consisting of zinc and carbon in sulphuric acid, or other exciting liquid.

y fine insulated wire, in which a momentary current is induced, when a current (as from a voltaic battery), passing through the inner coil, is made, broken, or varied. The inner coil has within it a core of soft iron, and is connected at its terminals with a condenser; -- called also inductorium, and Ruhmkorff's coil.…

flame when the vapor is ignited. Weale. -- Arc lamp (Elec.), a form of lamp in which the voltaic arc is used as the source of light. -- Dëbereiner's lamp, an apparatus for the instantaneous production of a flame by the spontaneous ignition of a jet of hydrogen on being led over platinum sponge; -- named after the Ger…

A voltaic series of two or more large plates, producing a great quantity of electricity of low tension, and hence adapted to the exhibition of electro-magnetic phenomena. [R.]

The negative plate of a voltaic or electrolytic cell. Negative pregnant (Law), a negation which implies an affirmation.

er between them, for producing a current of electricity; -- commonly called Volta's pile, voltaic pile, or galvanic pile.

which the bather can wholly immerse himself. -- Plunge, or plunging, battery (Elec.), a voltaic battery so arranged that the plates can be plunged into, or withdrawn from, the exciting liquid at pleasure.

An effect produced upon the plates of a voltaic battery, or the electrodes in an electrolytic cell, by the deposition upon them of the gases liberated by the action of the current. It is chiefly due to the hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro-motive force, bo…

ity which is developed when glass is rubbed with silk, or which appears at that pole of a voltaic battery attached to the plate that is not attacked by the exciting liquid; -- formerly called vitreous electricity; -- opposed to Ant: negative electricity. -- Positive eyepiece. See under Eyepiece. -- Positive law. See…

A connecting wire of an electric or voltaic apparatus, traversed by a current.

Of or pertaining to voltaic electricity, or voltaism.

ectricity 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.

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.

A form of voltaic, or galvanic, battery suitable for use electrotyping. G. Francis.

A voltaic battery in which the exciting fluid is water.
