Heh, give him a break. At least he admitted he got
it wrong, which is something rare here. But he's kind of
gotten it wrong a second time. He seems to be ignoring skin
effect. With DC, the current density is uniform in a wire.
As the frequency increases, the current distribution moves
toward the surface. At very high frequencies, most of it is traveling
at or near the surface. The wire could be mostly hollow and it would
carry almost the same current.




Ah, I see. Would this be true regardless of voltage or amperage?

I believe so. Skin effect is most pronounced at very high
frequencies, and virtually non-existent at low frequencies and DC. A
hollow conductor has 2 surfaces - not sure if the inner surface comes
into play or not.
