Cathode - Wikipedia
WEBA cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes the direction in which positive charges move.

Cathode And Anode - Definition, Examples and Key Differences …
WEBCathode: The anode is the electrode where electricity moves into. The cathode is the electrode where electricity is given out or flows out. The anode is usually the positive side. A cathode is a negative side. It acts as an electron donor. It acts as an electron acceptor. In an electrolytic cell, oxidation reaction takes place at the anode.

Cathode - Simple English Wikipedia, the free encyclopedia
WEBA cathode is a type of electrode through which electrons move. Electrodes are an electrical conductor (usually a metal) that is connected to something that is not a metal. Electric current is a flow of charges through a conductor.
Cathode-ray tube - Wikipedia
WEBA cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen.
Definition and History of Cathode Ray - ThoughtCo
WEBUpdated on April 16, 2018. A cathode ray is a beam of electrons in a vacuum tube traveling from the negatively charged electrode (cathode) at one end to the positively charged electrode ( anode) at the other, across a voltage difference between the electrodes. They are also called electron beams.
