| Noun | 1. | anode - a positively charged electrode by which electrons leave an electrical device electrode - a conductor used to make electrical contact with some part of a circuit electrolytic cell - a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen) plate - the positively charged electrode in a vacuum tube electron tube, thermionic tube, thermionic vacuum tube, thermionic valve, vacuum tube, tube - electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope cathode - a negatively charged electrode that is the source of electrons entering an electrical device |
| 2. | anode - the negatively charged terminal of a voltaic cell or storage battery that supplies current storage battery, accumulator - a voltaic battery that stores electric charge terminal, pole - a contact on an electrical device (such as a battery) at which electric current enters or leaves galvanic cell, primary cell, voltaic cell - an electric cell that generates an electromotive force by an irreversible conversion of chemical to electrical energy; cannot be recharged cathode - the positively charged terminal of a voltaic cell or storage battery that supplies current |
