In practice though, theres no such thing as a perfect conductor.
Yeah, as the frequency increases the charge density increases and the electrons are observed at the surface of a 'Perfect' conductor.
However in DC vehicle applications we use stranded 'flex' as this increases the total surface volume, reducing the need for massive solid core cables. Obviously there's the requirement for it to be flexible also.
I love a good physics discussion, but it doesn't help the OP
