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.

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

The center of the volta, ring, or manege ground, around which a horse turns. From pillar to post, hither and thither; to and fro; from one place or predicament to another; backward and forward. [Colloq.] -- Pillar saint. See Stylite. -- Pillars of the fauces. See Fauces, 1.

telltale lamp on a dynamo or battery circuit to show approximately by its brightness the voltage of the current.

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 -- Plunge, or plunging, battery (Elec.), a voltaic battery so arranged that the plates can be plunged into, or withdrawn from, the exciting liquid at pleasure.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

d function of living tissues, etc.; -- called also natural science, and physical science. Voltaire hardly left a single corner of the field entirely unexplored in science, poetry, history, philosophy. J. Morley.

, an apparatus for producing from a given electrical current another current of different voltage.

A voltaic battery in which the exciting fluid is water.

c; -- said of the electricity of the zincous plate in connection with a copper plate in a voltaic circle; also, designating the positive pole. [Obs.]
