In physics and electromagnetism, Gauss's law, also known as Gauss's flux theorem, (or sometimes simply called Gauss's theorem) is a law relating the distribution of electric charge to the resulting electric field. In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of ho… WebOct 9, 2014 · Zero divergence of Electric field. Is this what your looking for? ρ would be zero say, outside of a point charge. One of the paradoxes you'll find when considering a point charge is that the divergence is zero for the field created a point charge, except at the origin in which case it is undefined. This paradox is resolved using the dirac ...
