Cathode

ChemistryElectrode where electrons are gained (reduction) in redox reactions.ElectronicsIn a semiconductor diode, the terminal to which positive charge carriers flow internally and into which negative charge carriers enter from the external circuit. In electron tubes, the electrode from which electrons are emitted into the inter-electrode space.

cathode

The electrode of an electrolytic cell at which reduction is the principal reaction. (Electrons How toward the cathode in the external circuit.) Typical cathodic processes are taking up electrons and being discharged, oxygen being reduced. and the reduction of an element or group of elements from a high Cl a lower valence state.

Cathode

The fundamental negatively-charged electrode (positive pole) in a radio valve or radio tube; opposite to anode. Sometimes referred to as a ‘filament`, especially in a diode.

Cathode

The electrode in an electrochemical cell where reduction takes place, gaining electrons. During discharge the positive electrode of the cell is the cathode. During charge the situation reverses and the negative electrode of the cell is the cathode.
