A changing electrical current (AC) experiences the skin-effect where the electricity flows more easily in the surface layers. The higher the frequency the thinner the surface layer that is usable in a wire. At normal household AC (50/60hz) the skin depth is about 8-10mm but a...
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.
