Solid V Stranded wire

Over in the Cable Run thread:

There is mention of solid wire having less resistance.
I have heard this before around here and for some reason;
I thought that stranded wire had less resistance.
Something about more surface area. Is my memory going?
It' s been a long time since my electronics classes. We were still learning tubes.

Actually what they are referring to in the thread above, is using cable with a solid copper core vs. a copper plated wire core. The solid copper will have lower DC resistance than the plated.
The resistance of wire for a given length and material is determined by the cross sectional area. I believe that the difference between solid and stranded is negligible.

Thanks; That sounds better.
