what is resistivity ? class X physics question please tell detailed answers ​

Answer 1

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

Answer 2

Explanation:

The resistivity of a material is defined as the resistance of material having unit length and unit cross sectional area.

Its value is specific for a specific material. It is a property of a substance but resistance is a property of an object.
