cathode -
a negatively charged electrode that is the source of electrons entering an electrical device
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)
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 electrode through which current flows out of a device or cell.
cathode -
Considered incorrect usage by some the terminal through which current flows out of a diode when current is in the forward direction regardless of the direction the current is actually flowing.
Wikipedia
A cathode is an electrode through which electric current flows out of a polarized electrical device. Mnemonic: CCD (Cathode Current Departs). A widespread misconception is that cathode polarity is always negative.
