Unformatted text preview: librium. Conductors in Equilibrium •  The conductor has an excess of posi,ve charge. •  All of the charge resides at the surface. •  E = 0 inside the conductor. •  The electric field just outside the conductor is perpendicular to the surface. •  The poten,al is a constant everywhere on the surface of the conductor. •  The poten,al everywhere inside the conductor is constant and equal to its value at the surface. The Electron Volt •  The electron volt (eV) is defined as the kine,c energy that an electron gains when accelerated through a poten,al difference of 1 V. –  Electrons in normal atoms have energies of 10’s of eV. –  Excited electrons have energies of 1000’s of eV. –  High energy gamma rays have energies of millions of eV. •  1 eV = 1.6 x 10- 19 J Equipoten,al Surfaces •  An equipoten1al surface is a surface on which all...
