An electron gun is a part of cathode ray tube on increasing the
filament current the rate of emission of electrons from the cathode
will increase. on the other hand, by increasing the accelerating
potential on anode, the energy of electrons reaching the anode will
increase due which the electrons will strike the screen with a greater
speed.
