Nothing aimed at Charles here, but I do have to mention that there are potential problems with some "cheapie" wire. I just came across some no-name clear jacket zip cable that had one silver colored conductor and one copper colored conductor. I say 'had' because the silver colored conductor still looks fine, but the copper colored conductor is a greenish-bronze color
for the entire length of the cable.
The jacket must have reacted with the metal, and allowed/caused the cable to deteriorate right inside the jacket. A VOM measured significant resistance, obviously. YMMV, of course.
Here's an example pic I found on line (guess it's happened before), not of my cable:
