Question

what is resistivity? ​

Answer 1

Answer:

resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area.

Answer 2

Answer:

Electrical resistivity and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ.
