What would have happened if electron was considered positive?

Question

We always keep on telling that current flows opposite to electron, since electron is negatively charged. And old people didn't knew, that it is electron which actually flows..

So, now if we correct them and change the convention. And consider electron as positive, what will happen?

Will our laws get mutated?

Is there a reason of taking electron negative and proton positive?

Answer 1

Obviously our laws have to change. Because we redefine the direction of current and leave the direction of magnetism unaffected, the result must be that right-hand rule changes into a left-hand rule. After all, reality does not change. Electrons moving in a given direction still cause the same magnetic fields.
