Electron Volt Electron Volt (eV): The kinetic energy an electron gains when it accelerates through a potential difference of 1 V. The electron volt is a unit of energy: 1 eV = 1.60 x 10-10 J. The unit is commonly used for atomic scales. The ground state of Hydrogen has energy -13.6 eV. Energy = Charge x Volts 1 eV 1.60×10-19 CV-1.60×10-19 J Work and electric potential Work done on a charge: The work done on a charge q to move it from point A to point B in an electric field is the (negative) product of the electric potential difference, V-VA, and the charge q. WE-q(VB-VA) NOTE: No network is required to move a charge between two points with the same potential V. For conductors, this leads to: All points on the surface of a conductor are at the same potential V. • The potential inside a conductor is equal to its value on the surface of the conductor. Capacitors (charge) a device that can store electrical E in such a way that it can be reclaimed later.
