Problem

The resistivity of a nichrome wire at

20^{\circ}\text{C}

1.1\times 10^{-6}\,\Omega\,\text{m}

. Calculate its conductivity at the same temperature. a)

1.1\times 10^{6}\,\text{S m}^{-1}

9.1\times 10^{-7}\,\text{S m}^{-1}

9.1\times 10^{5}\,\text{S m}^{-1}

1.1\times 10^{-5}\,\text{S m}^{-1}
