Electron Volt

a unit of energy equal to the work done on an electron in accelerating it through a potential difference of one volt.

To put it in perspective

You can imagine that the electron starts at the negative plate of a parallel plate capacitor and accelerates to the positive plate, which is at one volt higher potential.

Numerically one eV equals 1.6x10-19 joules or a joule is 6.2x1018 eV.

For example, it would take 6.2x1020 eV/sec to light a 100 watt light bulb.”
