Question

What is resistivity explain with an.example

Answer 1

Dear student, Resistivity is the measure of a material’s ability to oppose the flow of current . Resistivity of a conductor is a property of the material of the conductor. Unit of resistivity is Ohm meter, Ω m . Resistivity of the material of the conductor changes with temperature. E.g , Resistivity of copper is 1.7 × 10^-8 Ω m at room temperature. Regards
