This article is about Gauss's law concerning the electric field. For analogous laws concerning different fields, see Gauss's law for magnetism and Gauss's law for gravity. For the Ostrogradsky–Gauss theorem, a mathematical theorem relevant to all of these laws, see
Divergence theorem.
In electromagnetism, Gauss's law, also known as Gauss's flux theorem or sometimes Gauss's theorem, is one of Maxwell's equations. It is an application of the divergence theorem, and it relates the distribution of electric charge to the resulting electric field.
