Classified under:
Nouns denoting man-made objects
Hypernyms ("electrode" is a kind of...):
conductor (a device designed to transmit electricity, heat, etc.)
Hyponyms (each of the following is a kind of "electrode"):
anode (a positively charged electrode by which electrons leave an electrical device)
base ((electronics) the part of a transistor that separates the emitter from the collector)
cathode (a negatively charged electrode that is the source of electrons entering an electrical device)
collector (the electrode in a transistor through which a primary flow of carriers leaves the region between the electrodes)
electron gun (the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it)
emitter (the electrode in a transistor where electrons originate)
control grid; grid (an electrode placed between the cathode and anode of a vacuum tube to control the flow of electrons through the tube)
Holonyms ("electrode" is a part of...):
battery; electric battery (a device that produces electricity; may have several primary or secondary cells arranged in parallel or series)
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))
electronic equipment (equipment that involves the controlled conduction of electrons (especially in a gas or vacuum or semiconductor))
electron tube; thermionic tube; thermionic vacuum tube; thermionic valve; tube; vacuum tube (electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope)
