But which way does that current flow in that wire? There are two possibilities depending on whether you’re thinking in terms of electron current or conventional current. In a circuit connected ...

Just an interest of mine I guess. As a professor of electronics, once full time and now an adjunct, I teach that current is electron flow then switch over to teaching a positive to negative flow ...

then ran a current through it and measured electron flow. In standard materials like gold, the electrons would always flow in the same general direction, even as they spread out into the chambers ...

However, it is not affected by electron–electron scattering ... As a result, there is a voltage gradient along the direction of current flow. Unfortunately, this local voltage gradient is ...
