How many volts does a cathode ray tube emits?

  1. Mar 10, 2015 #1
    I don't know a lot about classical physics but I was wondering how many volts a cathode ray tube emits?

    A cathode ray tube accelerates a beam of electrons which can get about 10 keV of energy, that is the difference of potential is about 10 kV, obtained transforming the alimentation voltage.
    The tube emits visible light colliding electrons of the pixels.
    The emission of x rays, due to the bremsstrahlung radiation, of the last monitor was very reduced in respect to international directives.

    Volts are nothing to be emited, but they are the moving force of electrons just like gravity
