The Physics of Electricity


Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?

Given how that the term determined is used, as in...

determined by the dielectric or insulation material

...and the definition of determined as used implies...

ascertain or establish exactly, typically as a result of research or calculation


Mr Geoff has a point....and a good one....not to say there isn't some affect, which there is, but definitely not ascertained or established exactly....or wholly.

Just sayin’ eh.
More to the point - the signal does not (rpt not) travel on the outside of the copper conductor. Even though the signal is comprised of photons. The basic understanding of how electricity works eluded the Belden engineer. He was probably an intern anyway.
Taras22, I can certainly understand your reluctance to say something a little more uh, authoritative on the dodgy subject of electricity. 😛
