K.C.S.E Physics Q & A - MODEL 2009PP2QN11

​ In an X- ray tube it is observed that the intensity of X- rays increases when potential differences across the filament is increased. Explain this observation 

answer

•  Increases in P d increases 1 in filament OR. Increase in P d increases heating effect this produces more electrons by Thermionic Emission.
• Hence results on more intense x - rays
