Answer:
One electron volt is the work done in taking one electron from one point to the other when the potential difference between these points is 1 volt.
Explanation:
Electron volt is a very small unit of work or energy, which is used in atomic physics. 1 electron volt is the kinetic energy which an electron acquires when accelerated through a potential difference of 1 volt.
