cathode

Kathode

An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows outwards (and thus, electrons flow inwards). It can have either a negative or a positive voltage with respect to anode of the same polarized device (depending on whether the device is a load or a source, respectively)

Kathode

The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode

Kathode

The electrode from which electrons are emitted into a vacuum tube or gas-filled tube

Kathode
