Question

Electron comes from where in cathode ray tube ?

Answer 1

electron produce from cathode ray tube by produce electricity with high voltage and so air will be brake down and ionization of is occurs ionization is that in which electro remove from element and we know that element is in air by n2 h2 o2 he etc. so dielectric breakdown by high voltage that produce electron and electron than motion in direction of high voltage to low voltage and we know that anode has high voltage by positive charge and cathode has low voltage by negative charge so than electron go to direction of cathode
