In electronics, a vacuum tube , an electron tube , or just a tube (North America), or valve is a device that controls electric current between electrodes in an evacuated container.

Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a heated cathode. This type is called a thermionic tube or . The vacuum tube is often used to amplify weak currents or act as a one-way valve (rectifier) for electric current.

An often neglected area of study in modern electronics is that of tubes, more precisely known as vacuum tubes or electron tubes. Almost completely overshadowed by semiconductor, or “solid-state” components in most modern applications, tube technology once dominated electronic circuit design. In fact, the historical . Electron tube , also called vacuum tube , device usually consisting of a sealed glass or metal-ceramic enclosure that is used in electronic circuitry to control a flow of electrons. Among the common applications of vacuum tubes are amplification of a weak current, rectification of an alternating current (AC) to direct current (DC), . In electronics, vacuum tube , electron tube , tube, or valve is a device that controls electric. Electron tube definition: an electrical device, such as a valve , in which a flow of electrons between electrodes.

A vacuum tube (also called an electron tube or, in the UK, a valve) is a device sometimes used to amplify electronic signals. In most applications, the vacuum tube is obsolete, having been replaced decades ago by the transistor. English dictionary definition of electron tube.

A sealed enclosure, either highly evacuated or containing a controlled quantity of gas, in which electrons can be made sufficiently mobile to act as the. An electron tube from which all or most of the gas has been remove permitting electrons to move with low interaction with any remaining gas molecules. It is used to create the Logger machine.

A wide variety of electron tubes have used radioactive material: voltage regulators, spark-gap tubes, voltage sensitive switching tubes, glow lamps, etc. In general, such tubes consist of a glass envelope, a fill gas, a radioactive source, an anode and an unheated (cold) cathode. Electron Tubes were introduced when Forestry was added to Feed the Beast.

Musk is seeking to revolutionize transportation by sending passengers and cargo packed into pods through an intercity system of giant vacuum tubes known as the “hyperloop.
