Detailed Solution

“Resistivity is defined as the resistance offered by the material per unit length for a unit cross-section. The SI unit of resistivity is

ohm metre

.”
Resistivity increases linearly with temperature.
For a conductor, the range of resistivity varies from

10^{- 8} Ωm - 10^{- 6} Ωm .

For an alloy, the range of resistivity varies from

10^{- 6} Ωm .

For an Insulator, the range of resistivity varies from

10^{12} Ωm - 10^{17} Ωm .
