Answer 1

Answer:

hy your answer

Explanation:

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.

mark it on brilliant dear ✌

Answer 2

Answer:

Resistivity of the material is defined as the resistance offered to current flow by a conductor of unit length having unit area of cross-section. Unit is ohm-metre(Ωm).

ρ= RA/l
