Which of the following has the lowest resistivity? A) Copper B) Paper C) Intrinsic Silicon D) Aluminium Revered Members, The above question appeared in my school exam and i could not find the right answer. Using google, i found the resistivity as follows copper --- 1.7E-8 ohm metre Silicon----2300 ohm metre Aluminium --- 2.7E-8 ohm metre But i could not get the value for paper. Paper catches fire so easily, so i assume that paper has lowest specific resistance, though i am not sure, if specific resistance includes both thermal and electrical resistance. I solicit the members' help for the correct answer.
