Definition of Cathodes

Cathode
Cathode Cath"ode, n. [Gr. ? descent; ? down + ? way.] (Physics) The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode. --Faraday. Cathode ray (Phys.), a kind of ray generated at the cathode in a vacuum tube, by the electrical discharge
