Question

Which of the following orders is correct regarding the electrical resistivity ($\rho$) of typical materials at room temperature?

Professor PC Thomas Classes · Answer

Metals have very low resistivity ($10^{-2}-10^{-8}\Omega m$), semiconductors have intermediate resistivity, and insulators have very high resistivity ($10^{11}-10^{19}\Omega m$).
