Electrical resistivity of a given metallic wire depends upon a. its length b. its thickness c. its shape d. nature of the material
Answers (1)
Resistivity of material does not depend on length, thickness and shape of the material.
Electrical resistivity of a given metallic wire depends on number density of free electrons in the conductor,
which is the nature of the material.
where, n = number of free electrons per unit volume.
Electrical resistivity also depends on the temperature of conductor.
Therefore, option (d) is correct.
