One of the mysteries of the English language finally explained.
A unit of energy equal to the work done on an electron in accelerating it through a potential difference of one volt.
- ‘Then if these electrons are attracted to a second plate B with a voltage (relative to A) of +1 volt, each electron gains one electron volt.’
- ‘One electron volt is roughly half the energy carried by a single photon of red light.’
- ‘Its decay produces gamma rays with energies of a trillion electronvolts.’
- ‘It means that the energy of the source is of the order of a teraelectronvolt, that is, a trillion electronvolts.’
- ‘At today's accelerators, for example the CERN LEP accelerator, the value has been measured as 1/128 rather than 1/137 at energies corresponding to approximately 100 billion electronvolts.’
