It relates the net electric flux to net electric charge enclosed in a surface. Mathematically, it is expressed as. Where →E E → is the electric field and Qenclosed is the charge enclosed Most laws in physics are written in in **differential** **form** because it emphasizes locality, in some **form** or another. While the locality is of course still there in **integral** **form**, it's easier to see in **differential** **form**. **Integrals** are explicitly dependent on multiple positions/times, and you have to prove that it's local

A fundamental result of classical electromagnetism is that Maxwell's equations imply that electric charge is locally conserved. Here we show the converse: Local charge conservation implies the local existence of fields satisfying Maxwell's equations. This holds true for any conserved quantity satisfying a continuity equation. It is obtained by means of a strong form of the Poincaré lemma. Furthermore, by applying the divergence theorem to the 1st term, we can re-write the equation as Equation 2: continuity equation of electric charge in integral form Looking at this expression more closely, one finds that the integral in the second term is just the total charge confined inside the closed surface S , namely q , while the first.
