Why glow is not produced when pressure inside cathode tube is high?

Answers

Answered by shrutikn3562

Explanation:

When an electron passes through a 5kV electric field it will gain 5000 electron-volts in kinetic energy, but it is also loosing kinetic energy each time it collides with a gas atom. ... So there will be no glow above a certain gas pressure and no glow below a certain pressure.

Hope this helps you friend

Thank You
