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. The electric field is defined at each point in space as the force per unit charge that would be experienced by a vanishingly small positive test charge if held stationary at that point. As the electric field is defined in terms of force, and force is a vector (i.e. having both magnitude and direction), it follows that an electric field is a vector field.
