That is a quirky feature. That one tells you about the curl of the electric field. Now, depending on your knowledge, you might start telling me that the curl of the electric field has to be zero because it is the gradient of the electric potential. I told you this stuff about voltage. Well, that doesn't account for the fact that ...

"WebHowever, on some non-convex sets, there exist non-conservative vector fields $\bfG$ that satisfy $\curl \bfG = \bf 0$. (This is a special case of a much more general theorem that we will neither state nor discuss.) Sketch of proof. We already know that if $\bfG = \grad f$, then $\curl \bfG = \curl \grad f = \bf 0$.
