Riddle me this: how is carbon a conductor?


I'm confused....

M. Wolff has a powercords, and now interconnect cables, made with "carbon ribbon". But when I look up the conductivity of carbon, it's a thousandth of silver's. Almost the same delta for copper.

So why use this stuff in the signal path?

It makes no sense to me (other than he also uses silver) that this is a good design call. Is not what one hears with these designs the non-carbon conductor geometry rather than carbon ribbon?

Really, this is not a shot across your bow, Michael (or to any who is satisfied with the product), but an attempt to understand why use such a poor conductor in the signal path?

Curious, 'cause I'm in the market for IC's and power cords, and attempting to understand the product offerings.

There are a number of forms of carbon each with different physical and electrical characteristics. Think graphite and diamond. Graphite, the most common form is in the form of flat plates that have very different measurements depending on whether you measure across that flat surface or through the plate. Thus material processing can drastically alter the measurements if you process to align the crystals instead of allowing them to be random which is the common form measured. Technically graphite is a hexagonal crystal that tests quite differently along its central axis than across the flat plates.
