Electric field energy equation
WebFeb 20, 2024 · ELECTRON VOLT. On the submicroscopic scale, it is more convenient to define an energy unit called the electron volt (eV), which is the energy given to a fundamental charge accelerated through a potential difference of 1 V. In equation form, 1eV = (1.60 × 10 − 19C)(1V) = (1.60 × 10 − 19C)(1J / C) = 1.60 × 10 − 19C.
