an electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. hence, it has a value of one volt, , multiplied by the electron's elementary charge "e", therefore, one electronvolt is equal to 









































the electronvolt, as opposed to the volt, is not an si unit. the electronvolt (ev) is a unit of energy whereas the volt (v) is the derived si unit of electric potential. the si unit for energy is the joule (j).

the term "electric potential energy" is used to describe the potential energy in systems with time-variant electric fields, while the term "electrostatic potential energy" is used to describe the potential energy in systems with time-invariant electric fields.









































section::::definition.









































the electric potential energy of a system of point charges is defined as the work required assembling this system of charges by bringing them close together, as in the system from an infinite distance.









































^\mathbf{r} q\mathbf{e}(\mathbf{r'}) \cdot \mathrm{d} \mathbf{r'}/math,









































the electrostatic potential energy can also be defined from the electric potential as follows:
