What's the best material that can be used as a conductor?

Question

Ideally I want to say photonic energy in general but conductors for heat and electricity would do fine also.

Answer 1

I think that bronze, silver and gold would be good conductors. Cotton would also be a good conductor. :D :) ;) :P x keep smiling & hope this helps with any kind of homework, coursework or GCSE's x LOVE YOU x (Even though I don't know you looool):):P
