Question

Electrical resistivity of a given metallic wire depends upon *
1 point
its length
its thickness
its shape
nature of the material

Answer 1

Explanation:

Answer: (d) Electrical resistivity of a given metallic wire depends on number density of free electrons in the conductor which is the nature of material, i.e., number of free electrons per unit volume. It also depends on the temperature of conductor

Answer 2

Answer:

Nature of the material.

Explanation:

Electrical resistivity of a given metallic wire depends upon Nature of the material.
