In Benjamin Franklin’s experiments, he came up with the convention that we use today to define a “positive” charge. As it turns out, electrons, discovered much later, are negatively charged according to the convention. Lots of chemical and physical reactions involve electrons as charge carriers, so lots of physical phenomena have this weird opposite thing going on. E.g. electric current or “conventional current” flows in the opposite direction of electron current. Chemical reactions are also weird. Reduction reactions involve a reduction in electric charge, but gaining an electron. The model works just fine, but it can be tricky and/or annoying at times.

What if we just assume current flows from negative to positive?
