Question

Match the following:
Column II gives the order of resistivity for materials in column I

Answer 1

Resistivity will be maximum for an insulator and minimum for a superconductor. So for superconductor resistivity will be $0\Omega -m$. Then comes the value of conductor which is close to ${10}^{-8}\Omega -m$. Then comes the value of semiconductor which is in the order of ${10}^{-1}\Omega -m$. The resistivity of an insulator is maximum and in the order of ${10}^{16}\Omega -m$
