One of the elements which appear at the respective poles when a body is subjected to electro-chemical decomposition. Cf. Anion, Cation.

A unit of electromotive force equal to one thousand volts.

o-electric machine in which the field is maintained by permanent steel magnets instead of electro-magnets.

treats of the development of electricity by the action of magnets; -- the counterpart of electro- magnetism.

Pertaining to, or designating, a force producing magnetic flux, analogous to electromotive force, and equal to the magnetic flux multiplied by the magnetic reluctance.

ng a great quantity of electricity of low tension, and hence adapted to the exhibition of electro-magnetic phenomena. [R.]

One of the larger measures of electro-motive force, amounting to one million volts.

A measure of electro-motive force; the millionth part of one volt.

erator producing, or any system conveying or utilizing, two or more waves of pressure, or electromotive force, not in phase with each other; polyphase.

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

Colored rings formed upon a metal plate by the electrolytic disposition of copper, lead peroxide, etc. They may be produced by touching with a pointed zinc rod a silver plate on which is a solution of copper sulphate.

it is a resistance substantially equal to 109 units of resistance of the C.G.S. system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14.4521 grams in mass, of a constant cross-sectional area, and of the l…

A device for measuring the difference in phase of two alternating currents of electromotive forces.

A cell (as one of two electrodes embedded in selenium) which by exposure to light generates an electric current.

The art or process of making photo-electrotypes. Sir D. Brewster.

A page of stereotype, electrotype, or the like, for printing from; as, publisher's plates.

or dull metal with a thin plate of precious or bright metal, as by mechanical means or by electro-magnetic deposition.

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…

s; multiphase; as, a polyphase machine, a machine producing two or more pressure waves of electro-motive force, differing in phase; a polyphase current.

Electro-positive.
