Question

what is resistivity?​

Answer 1

Answer:

electrical resistance of a conductor of unit cross section area and unit length. a characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric current. high resistivity designates poor conductors.

Explanation:

Answer 2

Answer:

Materials are divided based on their conducting properties as conductor,semi conductors and insulators.The electrical resistance of a material is defined as the resistance of the material per unit

length and per unit cross sectional area at a specified temperature..
