The diagram shows an electron gun of a hot cathode ray tube.
A 6 V D.C. source and a 1000 V D.C. sourece are available. How will these sourece should be connected to the terminals of X and Y so as to obtain a focused beam of fast moving electrons?
6 V D.C. source applied to X to generate electrons and 1000V D.C. source applied to Y to accelerate electrons
A 6V D.C. source applied to X generates electrons in large numbers and 1000V D.C. source applied to Y accelerates the electrons.
