Hydro-electric machine (Physics), an apparatus invented by Sir William Armstrong of England for generating electricity by the escape of high-pressure steam from a series of jets connected with…

nsulated 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. -- Indu…

using its needle to deviate from its proper direction, especially on shipboard. -- Local battery (Teleg.), the battery which actuates the recording instruments of a telegraphic station, as distinguished from the battery furnishing a current for the line. -- Local circuit (Teleg.), the circuit of the local battery. -…

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…

h 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 Municipa…
