imp. of Tread. On burnished hooves his war-horse trode. Tennyson.

The positive pole of a voltaic battery.

imp. & p. p. of Bestride.

The negative electrode or pole of a voltaic battery. Faraday.

In two figures having relative motion, one of the two curves which are the loci of the instantaneous center.

The path by which electricity is conveyed into or from a solution or other conducting medium; esp., the ends of the wires or conductors, leading from source of electricity, and terminating in the medium traversed by the current.

An excursion. [Obs.] "Outrodes by the ways of Judea." Macc. xv. 41 (Geneva Bible).

See Strude. [Obs.]

The condition of decreased irritability of a nerve in the region of the positive electrode or anode on the passage of a current of electricity through it. Foster.

The positive pole of an electric battery, or more strictly the electrode by which the current enters the electrolyte on its way to the other pole; -- opposed to cathode.

ndition of increased irritability of a nerve in the region of the cathode or negative electrode, on the passage of a current of electricity through it.

To tread down; to trample upon. [Obs.] In hell shall they be all fortroden of devils. Chaucer.

A glass tube provided with platinum electrodes, and containing some gas under very low tension, which becomes luminous when an electrical discharge is passed through it; -- so called from the name of a noted maker in germany. It is called also Plücker tube, from the German physicist who devised it.

A highly exhausted glass tube with metallic electrodes nearly in contact so as to exhibit the insulating effects of a vacuum. It was used by the German physicist W. Hittorf (b. 1824).

ates the feet of certain animals, as horses, oxen, etc. On burnished hooves his war horse trode. Tennyson.

ide with a horse, or with horses; to mount on, or as on, a horse. "Being better horsed, outrode me." Shak.

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

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…

One of the poles of a voltaic battery; an electrode.

To join, as the electrodes of a battery or dynamo or any two points of a circuit, by a conductor of low resistance.
