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. This type is called a thermionic . Vacuum_tube Önbellek Benzer Bu sayfanın çevirisini yap A vacuum tube , also called a valve in British English, is an electronic device used in many older model radios, television sets, and amplifiers.
