Vedclass · Answer

(A) The electrical conductivity of solids is classified based on their ability to conduct electricity. Metals are excellent conductors of electricity with conductivity in the range of $10^7 \ \Omega^{-1} \ m^{-1}$. Semiconductors have intermediate conductivity ranging from $10^2$ to $10^9 \ \Omega^{-1} \ m^{-1}$. Insulators have very low conductivity,typically ranging from $10^{-20}$ to $10^{-10} \ \Omega^{-1} \ m^{-1}$. Therefore,the correct order is $Metals > Semiconductors > Insulators$.
