Question

What is the resistivity range for metals (conductors)?

Options

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

• \[10^{2}\text{ to }10^{8}\ \mathrm{S}\cdot\mathrm{m}^{-1}\]

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

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

Answer 1

Metals have the low resistivity range \[10^{-8}\] to \[10^{-2}\ \Omega\cdot\mathrm{m}\]. This low resistance to electrical flow makes them conductors.
