Question

Electrical resistivity of a given metallic wire depends upon its

Length

Shape

Nature of the material

Thickness

​

Answer 1

Answer:

All of the above except Shape

Answer 2

Answer:

NATURE

OF THE

MATERIAL

Explanation:

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.
