EV has various meanings in the Scientific & Educational category. Discover the full forms, definitions, and usage contexts of EV in Scientific & Educational.
The electron volt is a unit of energy equal to approximately 160 zeptojoules (symbol zJ) or 1.6×10−19 joules (symbol J). By definition, it is the amount of energy gained (or lost) by the charge of a single electron moved across an electric potential difference of one volt.
Scientific & EducationalAn electronvolt is defined as 1.6022 × 10⁻¹⁹ Joules. The energy needed to move an electron from a metal electrode at voltage V1 to an electrode at voltage V2 is V1 - V2 electron volts. One electronvolt is about the amount of energy needed to dissociate a molecule.
