I know for AC, the push-pull forces the electrons to the outside of the wire (skin effect) but for DC, in a solid wire, does it only travel on the outside of the wire, or will it 'fill' the wire. The background of the question is, a busbar attached to a PCB, where a stud ties it to the "pad". From talking to some in the bus bar industry who alluded to the fact when a stud ties into a bar, the current only really carries on the outside of the stud, and the actual transfer of current happens primarily on the surface to surface contacts of the pad and the bar.
