Electrical resistivity of a given metallic wire depends upon

1. its length
2. its thickness
3. its shape
4. nature of the material

Answer

The resistivity of a material is constant for a particular temperature at a constant temperature. Resistivity of material does not depend on length, thickness and shape of the material. It only depends on the temperature.

The correct option is D.
