Answer 2

Answer:

Electricity is a flow of electrons. Electrons can flow across a vacuum. ... They need to leap because the vacuum is a perfect insulator and so there is no medium in which they can flow (like through a metal conductor) so they must aquire all of the energy necessary to cover the distance before they can escape the cathode
