That branch of electrical science which treats of the effect of an electric current upon the temperature of a conductor, or a part of a circuit composed of two different metals.

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 this is then the plate for printing.

Derived from, or dependent upon, vital processes; -- said of certain electric currents supposed by some physiologists to circulate in the nerves of animals.

The theory that the functions of living organisms are dependent upon electricity or a kindred force.

1893 and by U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver in water, deposits silver at the rate of 0.001118 grams per second. Called also the i…

An electro-negative element, or the element which, in electro- chemical decompositions, is evolved at the anode; -- opposed to cation. Faraday.

A piece of soft iron used to connect the two poles of a magnet, or electro-magnet, in order to complete the circuit, or to receive and apply the magnetic force. In the ordinary horseshoe magnet, it serves to prevent the dissipation of the magnetic force.

Pertaining to, or having the nature of, a basyle; electro- positive; basic; -- opposed to chlorous. Graham.

An instrument for regulating the electro-motive force in an alternating-current circuit; -- so called because used to "boost", or raise, the pressure in the circuit.

was the first element discovered by spectrum analysis, and is the most strongly basic and electro-positive substance known. Symbol Cs. Atomic weight 132.6.

An electro-positive substance, which in electro-decomposition is evolved at the cathode; -- opposed to anion. Faraday.

Pertaining to, or resembling, the electro-negative character of chlorine; hence, electro-negative; -- opposed to basylous or zincous. [Obs.]

s. It is the quantity of electricity conveyed in one second by the current produced by an electro-motive force of one volt acting in a circuit having a resistance of one ohm, or the quantitty transferred by one ampère in one second. Formerly called weber.

powerful shocks; -- called also sheathfish. -- Electric clock. See under Clock, and see Electro-chronograph. -- Electric current, a current or stream of electricity traversing a closed circuit formed of conducting substances, or passing by means of conductors from one body to another which is in a different electric…

s or machine for producing motion and mechanical effects by the action of electricity; an electro-magnetic engine.

An abbreviation for electro-motive force.

standard unit of electrical capacity; the capacity of a condenser whose charge, having an electro-motive force of one volt, is equal to the amount of electricity which, with the same electromotive force, passes through one ohm in one second; the capacity, which, charged with one coulomb, gives an electro-motive force o…

Same as Electro-puncture.

An electro-negative element or radical, which, by combination with a metal, forms a haloid salt; especially, chlorine, bromine, and iodine; sometimes, also, fluorine and cyanogen. See Chlorine family, under Chlorine.

The unit of electric induction; the induction in a circuit when the electro-motive force induced in this circuit is one volt, while the inducing current varies at the rate of one ampère a second.
