How a tube light formed?
tube light us formed by sum inerts gasses like neon because they do not react with electron and the friction between electron and neon produced light.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
What is filament current?
The current supplied to the filament of an electron tube for heating.
What is the evidence that an electron carries an electric charge?
the deflection of an electron beam in a cathode ray tube by electric and magnetic feilds.
What is in a vacuum tube?

At what time was diversification of electron tube application begun?
After World War II, U.S. electron tube manufacturers found a diverse and lucrative market in defense applications, ranging from radar to communication and control equipment.
Who are the industry leaders in electron tube manufacturing?
the leading firms in the electron tube industry in the 1990s were Zenith Electronics Corporation, Philips Display Components Company, Hitachi Electronic Devices, and Toshiba Westinghouse Electronic.
