Moving an electron within an electric field would change the ___________the electron.
When a force is required to move an electron in the direction of an electric field, its electrical potential energy increases. On the other hand, an electron moving opposite the direction of the electric field will decrease its electrical potential energy.
Which one of the following statements is false?
