The probability current is invariant under gauge transformation . …
NettetNet charge density is independent of current density: There could be a set of fixed positive background charges that cancel the charge contribution of moving negative charges (that create current), so the net charge density is zero. (This case is exactly that of a current-carrying wire.) There might be only the moving charges. NettetA = 0 .
