Question

How does resistance specific resistance of a wire depends on its length and radius?

Answer 1

$\huge\mathfrak\red{AnSweR}$

Resistance of a material is directly proportional to its length and inversely proportional to the square of the radius of the wire . Now look the resistivity of a wire depends on the material of the wire so resistivity of a wire is independent of its length and radius

Answer 2

AnSweR

Resistance of a material is directly proportional to its length and inversely proportional to the square of the radius of the wire . Now look the resistivity of a wire depends on the material of the wire so resistivity of a wire is independent of its length and radius
