Homework Help: Distribution of charge question

  1. Feb 8, 2005 #1
    If you have a negatively charged conductor (let's say a sphere), are its excess electrons distributed evenly throughout it? I think they are uniformly distributed, but only on the surface. Is this true?

    YES, at equilibrium, the electric charge is distributed on the surface of conductors: inside a conductor the electric field intensity must be 0 => no electric charge (Gauss's law). For a sphere, they are indeed uniformly distributed on its surface but for other geometries the density charge will increase in the regions with smaller curvature radius.
