Why is the curl of an electric field zero? - Quora

WebHallo, on thing that confuses me is the relation to the electric field. For a positive divergence in a region short arrows must go in and longer must come out (Its only magnitude). The divergence of the electric field is equal to charge density over epsilon (Permittivity constant)* . div(*E) = p/e. But the electric field is going weaker and ...
