Answer: A vacuum tube, an electron tube, or valve (British usage) or, colloquially, a tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
Answer: An electronic device that controls the flow of electrons in a vacuum. It is used as a switch, amplifier or display screen (CRT). Used as on/off switches, vacuum tubes allowed the first computers to perform digital computations.
Answer: 1990s-Today - Vacuum tubes are still used today. Musicians still use tube amplifiers and claim they produce a different and desirable sound compared to solid state amplifiers.
Answer: The basic working principle of a vacuum tube is a phenomenon called thermionic emission. ... A simplified diagram of a vacuum tube diode. When the cathode is heated, and a positive voltage is applied to the anode, electrons can flow from the cathode to the anode.
