Copper conducts better than Gold?

thats right, but not price, it has no effect on resistivity. so many answers had nothing to do with the original question..the original question was whether gold had better conduction than copper.

In the following page:
http://www.allaboutcircuits.com/textbook/semiconductors/chpt-2/band-theory-of-solids/

The table (bottom of the article) lists resistivity of Gold, Copper and other materials.

It says that resistivity of Gold is higher than Copper..

No, the original post was not a question, the OP stated a simple fact.

And, the OP said nothing about conduction, he said "resistivity".

Additionally, You brought in the concept of "best". I simply said that I have trouble with the phrase "best" when there are obviously better options in certain circumstances.

Finally, I cannot figure out where in my previous posts that you see that I correlated a dollar per ohm factor. Look again. I used price per kilogram of material as a circumstance.

what is the diffference of conduction and resistivity? things that have low resistivity have high conduction. same thing, different label.

I'm glad to hear you are back on track. In an earlier post you made it seem as though you were differentiating resistivity as a false measurement for conductivity when you said...


going by the silly comparisons to compare resistivity is not scientific.

best conductor of electricity is a standard.based on resistivity.and resistivity is based on standard size conductors.
Huh?

Resistivity is a bulk property of the material and has nothing to do with the size and shape of the conductor. I think might be confusing "resistivity" with "resistance per unit length". The units of resistivity are resistance time length, though it is more accurately resistance-per-(length-per-area).

Hola William. At lost here. Could you elaborate briefly on the bold part?

\(\rho\;=\;R\frac{A}{l}\;=\;\frac{R}{\frac{l}{A}\)
The units of ρ are Ω⋅m

It is like saying that acceleration has units of length per second per second
