Cathode ray tube

  1. Feb 25, 2016 #1
    • suppose I connect a 10,000 v supply to a normal tube light. what will happen? will it behave like a cathode ray tube or something else

    So, what do you mean by "a normal tube light"?

    OK. The term is "fluorescent tube". Wikipedia says: "Connected directly to a constant-voltage power supply, a fluorescent lamp would rapidly self-destruct due to the uncontrolled current flow."

    then how to make a cathode ray tube , without using vacuum pump or tube because it will cost more,

    What do you want the cathode ray tube for?
  8. Feb 26, 2016 #7
    just to see the flow of electrons and its magnetic behaviour

    I'm sorry but high-voltage electricity and vacuums are dangerous to those without the proper training. If you'd like to continue this project then please find someone local to work with who is properly trained. Thread locked.
