People,
over the years I have been an Installer,this seems to be key.I have a basic or better then b asic understanding of what it means.
Simply put Ohms Law is a mathematical equation that shows the relationship between Voltage, Current and Resistance in an electrical circuit.
My question is really to all you Engineersw out there,can you go deeper on the subject?
Reason is a deeper understanding of wire.As usual my ever loving quest.
Ohms law is it in you?

V=I*R is our foundation and I hope we can all agree upon that. I'll speak to R and define it as rho*L/A. rho is the resistivity of the material(Gold,Silver,Copper), L is the lenth of the wire and A(-pi-R**2)is the diameter(guage.."2 is big while 20 is small"). I posted along time ago the difference between gold and siver that showed the investment is not worth it with silver. I am a firm believer that area is the governing specification while demonstrating cost to performance ratio's.
Enough for now, we'll see how this is received

LOL good question!
Just remember, you may be able to make the numbers come out in favor of one wire over another, but that doesn't mean you can actually hear a difference. Chances are you can't if both speaker wires are brand new and not damaged or ugh, green...
All you really need to know is how much current will those speakers need at max and make sure your wire is thick enough to deliever (assuming your amp can deliever the current), and if not bi-wire and make it thicker! I seriously doubt you can hear the difference between $1 a foot and $100 a foot wire if you set it up with a switch box and did a blind fold test. But you need to make a living and if people want it, sell em the $100 a foot wire! If they can afford it, then its just more money in the economy.

Howie,
Sent you an email via the link on your profile page, Did ya get it? -
I can't check it until I get home, but I will in 4-5 hours

... and inverse ohms are "mhos"...Originally posted by HBombToo
rho is the resistivity of the material
why aren't they "smhos"?
More later,

Tour,
They are not shmos because the deionized water would not have it that way!;)
On a more serious note, I was reading something last night about Analysis Plus cables and interconnects and they have some interesting theory on "skin effect" and "current bunching" on their website along with resistance, ohm's law, and so forth. They claim that they can actually model this phenomena as well. I've read good things about this wire company as well but I don't recall anyone here in the forum using these wires.

Did you find out all that you need to know? If you need to delve deeper into acoustical sound theories and practices, I don't think a basic mathmatic formula will give you the results you're looking for. There are too many variables.
Examples:
12 AWG stranded OFC sounds way differenent than does 12 AWG single strand OFC. They measure the same on any equipment I've come across, but the sound is totally different.
Silver plated sound different than copper for any given length, diameter, strand count, dielectric, etc.
Silver sounds different than (see above)
Gold sound different than (see above)
Platinum? Haven't tried it YET.
Here's one for ya. Take a couple pairs of RCA connectors. Build some 1m ICs. Make one set out of 14 AWG stranded copper and one set out of 28 AWG single or stranded copper. The results will defy the math.Make it Funky!
