Does length really matter?

Jstas

double post. disregard.

:rolleyes:I've been around long to know that you don't believe anyone can educate you, and my mockery was even lost on me I guess.

I am glad to know that when my 25 foot extension cord is overheating that a 50 foot one will cure the problem. Thank your professors for me.......Asshat.:rolleyes:

Terminology, referring to wiring gauge, a 14 AWG is a "larger gauge" than 12 AWG, but the diameter, cross section, and surface area of a 12 AWG are all larger. The SMALLER the Gauge, the bigger the wire. Both of you are arguing the same point, but your terminology is where the issue is. I took circuits, I graduated with a degree in Engineering (Mechanical), and believe me, wire with a larger surface area will have less resistance. I think this whole little debate is over a mis-understanding in terminology, heck, I have seen it before, between two electrical engineers, one was thinking larger gauge = larger cabling, the other, terminologically was correct, as he stated larger gauge = smaller cabling.

I get the gauge terminology confusion. I guess my misunderstanding is whether Jstas was quoting generalities or specific situations that cause specific resistance changes that don't exist in normal audio confines. According to his statement, a 12 ga wire has more resistance than a 24 gauge wire of the same composition. I just don't get that. If my understanding is wrong, that is cool too.

Resistivity increases with increasing temperatures in conductors, and decreases with increasing temperatures in insulators. As far as size of cabling, resistivity ALWAYS decreases as the cabling increases in size (or decreases in gauge), given that voltage, and amperage remain constant.

The impression I had was the OP wanted to know if there is a sonic difference in wire lengths, not resistance or any of the other electrical characteristics.

His question was "You think it makes a difference?" Obviously there will be some small electrical difference, but will it be audible. That is how I interpreted the post and question.
