WebApr 12, 2024 · An electron tube (also known as a 'Vacuum tube', or a 'Valve' ) is a glass or metal enclosure in which electrons move through the vacuum or gas from one metal electrode to another. The vacuum tube is often used to amplify weak currents or act as a one-way valve (rectifier) for electric current. The 19th century saw increasing research with evacuated tubes, such as the Geissler and Crookes tubes. The many scientists and inventors who experimented with such tubes include Thomas Edison, Eugen Goldstein, Nikola Tesla, and Johann Wilhelm Hittorf. With the exception of early light bulbs, such tubes were only used in scientific research or as novelties. The groundwork lai… WebIt worked by connecting a voltage source across a pair of wires that supported a filament inside a vacuum. The voltage caused electrons to flow into one wire, through the filament, and out from the other wire. The filament's resistance created heat that made the filament glow white hot. + _ electron flow flip it bottle emptying
