noun🔗ShareCathodeAn electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows outwards (and thus, electrons flow inwards). It usually, but not always, has a positive voltage."Electrons flowed into the cathode of the battery as it charged. "Les électrons ont afflué dans la cathode de la batterie pendant qu'elle se chargeait.electronicsphysicstechnologydeviceelectricmachinescienceChat with AIVocabulary GamePractice Reading
noun🔗ShareCathode(by extension) The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode."During electrolysis, copper ions in the solution move to the cathode, where they gain electrons and form a solid copper coating. "Pendant l'électrolyse, les ions cuivre dans la solution se déplacent vers la cathode, où ils gagnent des électrons et forment un revêtement de cuivre solide.chemistryelectronicsphysicsmaterialscienceelementChat with AIVocabulary GamePractice Reading
noun🔗ShareCathodeThe electrode from which electrons are emitted into a vacuum tube or gas-filled tube."In older televisions, the cathode inside the picture tube shot electrons onto the screen to create the picture. "Dans les téléviseurs plus anciens, la cathode à l'intérieur du tube cathodique projetait des électrons sur l'écran pour créer l'image.electronicsdevicetechnicalphysicsmachineenergyscienceChat with AIVocabulary GamePractice Reading
noun🔗ShareCathodeThat electrode of a semiconductor device which is connected to the n-type material of a p-n junction."In the LED circuit we built in class, the cathode, connected to the n-type semiconductor, was marked with a shorter lead. "Dans le circuit LED que nous avons construit en classe, la cathode, connectée au semi-conducteur de type n, était marquée d'une broche plus courte.electronicsdevicetechnologymaterialphysicsscienceChat with AIVocabulary GamePractice Reading
