Question

What is the resistivity range for insulators?

Options

• \[10^{-5}\text{ to }10^{6}\ \Omega\cdot\mathrm{m}\]

• \[10^{-8}\text{ to }10^{-2}\ \Omega\cdot\mathrm{m}\]

• \[10^{11}\text{ to }10^{19}\ \Omega\cdot\mathrm{m}\]

• \[10^{-19}\text{ to }10^{-11}\ \mathrm{S}\cdot\mathrm{m}^{-1}\]

Answer 1

Insulators have a very high resistivity of \[10^{11}\] to \[10^{19}\ \Omega\cdot\mathrm{m}\]. Consequently, they do not conduct under normal conditions.
