Vedclass · Answer

(A) The resistivity of a material determines its classification as a conductor,semiconductor,or insulator.Metals (conductors) have low resistivity,typically in the range of $10^{-2}$ to $10^{-8} \Omega-m$.Insulators have very high resistivity,typically in the range of $10^{11}$ to $10^{19} \Omega-m$.Semiconductors have resistivity values that lie between those of conductors and insulators,typically in the range of $10^{-3}$ to $10^6 \Omega-m$ (or $10^{-1}$ to $10^8 \Omega-cm$).Given the options provided,the range $10^{-3}$ to $10^6 \Omega-cm$ is the standard accepted range for semiconductors.
