Question

Difference between gauss law and divergence of vector flux density

Answer 1

Divergence is the microscopic version of Gauss's Law where the volume becomes a differential volume (like V→dV). if no one else does, i will write an answer that will be more conceptual and won't include Green's theorem. – robert bristow-johnson Dec 19 '16 at 19:34

Honors, it's gonna take awhile before i can organize it. maybe tonight. in the meantime, look up inverse-square law, Gauss's law, and the concept of flux and flux density. the divergence equation is another way of stating the behavior of "flux" of some physical quantity, and if that quantity is conserved in some manner, the inverse-square law comes out of that notion. And Gauss's law says the same conservation of flux more directly. – robert bristow-johnson Dec 19 '16 at 20:38
