Question

what is resistivity kindly explanation needed?!?!??​

Answer 1

$\large\underline{\pink{\sf \red{\dag} Understanding \:Concept \: Of \: Resistivity :-}}$

• ◈ Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.

• ◈ Materials that conduct electrical current easily are called conductors and have a low resistivity.

• ◈ Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.

Answer 2

Resistivity, electrical resistance of a conductor of unit cross-sectional 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 currents. High resistivity designates poor conductors.
