Divergence of electric displacement

WebNov 5, 2024 · Gauss’s law, also known as Gauss’s flux theorem, is a law relating the distribution of electric charge to the resulting electric field. The law was formulated by Carl Friedrich Gauss (see ) in 1835, but was not published until 1867. It is one of the four Maxwell’s equations which form the basis of classical electrodynamics, the other ... WebBy the Gauss divergence theorem, this means the rate of change of charge in a fixed volume equals the net current flowing through the boundary: ... In order to apply 'Maxwell's macroscopic equations', it is necessary to specify the relations between displacement field D and the electric field E, as well as the magnetizing field H and the ...
