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.
