Vacuum tube - Wikipedia
A vacuum tube, electron tube, [1][2][3] valve (British usage), or tube (North America) [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
The History and Importance of the Vacuum Tube - ThoughtCo
Feb 3, 2019 · A vacuum tube, also called an electron tube, is a sealed-glass or metal-ceramic enclosure used in electronic circuitry to control the flow of electrons between the metal electrodes sealed inside the tubes. The air inside the tubes is removed by a vacuum.

Vacuum Tube - Encyclopedia.com
May 11, 2018 · A vacuum tube is a hollow glass bulb, approximately cylindrical in shape, that contains a positive electrode and a negative electrode between which a current is conducted through a full or partial vacuum. A grid between the electrodes controls the flow of electricity.
Vacuum Tube Basics: Types, How They Work, Vacuum Tube vs …
Sep 22, 2023 · What are Vacuum Tubes? Vacuum tubes, sometimes referred to as electron tubes or valves, are a form of electrical device that regulates the flow of electric current between electrodes that have an electric potential difference applied to them while in a high vacuum.
Anatomy of a Vacuum Tube: Exploring the Schematic Diagram
A vacuum tube, also known as a thermionic valve, is an electronic component used to amplify, switch, or control electrical signals. It consists of a sealed glass envelope containing two or more electrodes, or “electrode elements”, which are surrounded by a vacuum.
What is vacuum tube and how does it work? - Physics Network
May 22, 2023 · A vacuum tube, also called a valve in British English, is an electronic device used in many older model radios, television sets, and amplifiers to control electric current flow. The cathode is heated, as in a light bulb, so it will emit electrons. This is called thermionic emission.
