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 Definition and Identification Tips - ThoughtCo
WebMay 7, 2019 · The cathode is the electrode from which electrical current departs. The other electrode is named the anode. Keep in mind, the conventional definition of current describes the direction a positive electric charge moves, while most of …
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 | Vacuum Tubes, Electrodes, Filaments | Britannica
Webcathode, negative terminal or electrode through which electrons enter a direct current load, such as an electrolytic cell or an electron tube, and the positive terminal of a battery or other source of electrical energy through which they return.
What is cathode? | Definition from TechTarget
WebA cathode is the metallic electrode through which current flows out in a polarized electrical device. Conversely, an anode is the electrode in a polarized electrical device through which current flows in from an outside circuit. Cathodes get their name from cations (positively charged ions) and anodes from anions (negatively charged ions).
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.
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. How Cathode Rays Works.
Cathode ray | electron beam, X-rays, TV tubes | Britannica
WebCathode rays focused on a hard target (anticathode) produce X-rays or focused on a small object in a vacuum generate very high temperatures (cathode-ray furnace). When cathode rays strike certain molecules used to coat a cathode screen, they cause the molecules (and hence the screen) to emit light.
