An electron volt is by definition the kinetic energy gained by an electron if it is accelerated through a potential difference of 1V, Consider now an electron accelerated in a potential difference of 5.0 V. The electron thereafter collides with a fictitious atom of the following energy diagram: see fig. 1 a) What is the kinetic energy of the electron before collision? b) At which highest energy level the atom can be excited? Represent this transition on the figure. c) What happens to the excess energy of the electron?
