August 12, 2010 University Physics, Chapter 22 46 Gauss’ Law ! Objective: So far, we have considered point charges How can we treat more complicated distributions, e.g., the field of a charged wire, a charged sphere, or a charged ring? ! Two methods: Method #1: Divide the distribution into infinitesimal elements dE and integrate to get the full electric field

Unformatted text preview: • Method #2: If there is some special symmetry of the distribution, use Gauss’ Law to derive the field Gauss’ Law The flux of electric field through a closed surface is proportional to the charge enclosed by the surface. First we need to define the concept of flux Thursday, September 2, 2010...
