Web1 Answer. You can't measure speed of electrons from these data alone. If the area of the cross section of a cylindrical conductor is A then the formula would be v = I Q e A where Q is the mobile electrons per cc and e is the charge of electron, v is the speed of electron, I is the current. This is for dc.
