Completed by February … WebVacuum tube. 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. The anode is the part that accepts the emitted ...
WebThe development of vacuum tubes was a major technological advancement that paved the way for the creation of the first computers. Vacuum tubes are devices that use a vacuum, or an evacuated space, to control the flow of electrons. They were invented in the early 20th century and were initially used in a variety of electronic devices, including ... A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry.
