To add one proton to the conductor would take only 1.6, The electric potential at a given point is the electric potential energy. Only one unit positive charge is taken into account in electric potential. kilogram per kilogram, which may be represented by the number 1. kg/kg = 1. This is the potential difference between two points on a conductor . electric potential energy electric field work electric potential difference, What is the electric potential at a distance of 1.2 m from a 7.5 C point charge?
