It is not about resistance, you stupid twit. It is about current flow, and heating. You know... what most in the US casually refer to as Ampacity. A term related to heat rise in conductors. Nicks, stretches, and ALL other manners of reduction of the cross sectional area of the wire are ALL the primary cause of failure in wiring.
A single nick in a wire, or a single missing strand is enough to cause a failure of acceptability in current worldwide electronic standards.
For a dope like you to come up with math that makes it appear as if you are saying that the change is very small and therefore can be ignored is
100% proof that it is you that doesn't know the first thing about it.Even your percentage numbers were guesstimations on your part, and you are pissing and moaning about my lack of use of math?
You are pathetic, John.
