anode Definition
an·ode (an′ōd′)
noun
- in an electroplating cell, the positively charged electrode, toward which current flows
- in an electron tube, the principal electrode for collecting electrons, operated at a positive potential with respect to the cathode
- in a battery that is a source of electric current, as a dry cell or storage battery, the negative electrode from which the electrons are released to the external circuit
Etymology: coined by Michael Faraday < Gr anodos, a way up < ana-, up + hodos, way: see -ode
