Vedclass · Answer

(B) The electrical conductivity $(\sigma)$ of materials is categorized based on their ability to conduct electricity.Metals are good conductors with high conductivity, typically in the range of $10^6$ to $10^8 \ S/m$.Insulators have very low conductivity, typically in the range of $10^{-10}$ to $10^{-20} \ S/m$.Semiconductors have conductivity values intermediate between conductors and insulators, typically in the range of $10^{-6}$ to $10^4 \ S/m$ depending on the material and temperature.Given the options provided, the range $10^2$ to $10^3 \ S/m$ is the most appropriate representation for semiconductors among the choices.

$LIST$ $I$	$LIST$ $II$
$A$. Intrinsic Semiconductor	$I$. Fermi-level near conduction band
$B$. $n$-type semiconductor	$II$. Fermi-level at middle
$C$. $p$-type semiconductor	$III$. Fermi-level near valence band
$D$. Metals	$IV$. Fermi-level inside conduction band

At ordinary temperatures, the electrical conductivity of semiconductors in $S/m$ (or $mho/m$) is in the range:
