"Electric current is carried mostly on the surface of a wire, so a conductor with a thousand fine strands has less resistance than the same gauge of wire with a hundred thicker ones."
Good morning Keroppi,
I checked the above quote with one of my sons who is a electrical engineer and he explained that how electricity travels is actually dependent on its frequency. He explained that it's the electrons that actually move in a conductor and electrons repel each other and stay as far apart as they can. How electricity flows is explained in this article:
