Just R * I^2, so at 10A 0.8W for copper or 3.2W for nickel.
Umm...how do I convert that to temp rise in the conductor?
Empirical or Virtual?
Virtually you can use BTU/Min calculations.
Empirical;

Thermal equations get very complicated. The question you are asking, earns the best of experienced engineers, about a quarter million dollars per year, or even much more when employed. I am impressed by the kind of questions you ask... they are great questions...
I ( am certain that I ) do know, but I want to check to see that I am correct before i lay it out here. Gimmie a min, and I'll see if I cannot let ya know how it works a little better.. ( gotta ask someone else who knows.. ) .. with the math.... ( I am not the best at the math.. ) ?!?!?!?!? Lol. Greek to me. Whats it mean? Idk.
For example, programs to do thermal modeling are very expensive.. typically.. cause only engineers use them and all engineering gets paid for or else there is no product... Sothere is no pirated thermal software.. anywhere....
( I wonder if there is a good free thermal modeling software? Huh IDK)
.... if you do not have a company license... ( ie 500$-1000$ for one program to do this, given opotons. .
(winsteam is an example..
)
Familiarize yourself with some of this information / concepts / equations... ;
