Question

What is the conductivity range for metals (conductors)?

Options

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

• \[10^{-6}\text{ to }10^{5}\ \mathrm{S}\cdot\mathrm{m}^{-1}\]

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

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

Answer 1

Metals have a conductivity of \[10^{2}\] to \[10^{8}\ \mathrm{S}\cdot\mathrm{m}^{-1}\]. Their large number of free electrons supports electrical conduction.
