Question

electrical resistivity of given metallic wire depends upon what ?
1.it's length.
2.it's thickness.
3.it's shape.
3.nature of the material .
give the answer with explanation . plzz.​

Answer 1

Answer:

3. nature of the material... as the resistivity depends on the material

Answer 2

Answer:

It depends only on the nature of the material.

Explanation:

Resistance depends upon the length of the wire and the area of cross-section or thickness but the electrical resistivity depends only on the nature of the material of the wire. Silver has the lowest electrical resistivity and therefore the best conductor.....I hope you understand
