BRAINCAKEThe Electron Volt
The energy of small particles is often expressed in millions of electron volts.
One electron volt is the energy transferred when an electron is moved through a potential difference of 1 volt.
The definition of potential difference is V = W/Q. i.e potential difference is work done per unit charge.
