I think all the answers can be found there. Amazing what you can find at
www.google.com in 2 minutes. Note the link that had electric properties. It shows a resistance number that I think answers your question but I am not sure if higher resistance means it disapates more or less energy (heat) than the lower resistance. I would think less resistance means it flows better meaning it disapates faster but not sure.
Of course I can totally be wrong with this aswell. :shrug:
