Electrical resistivity of a given metallic wire depends upon (1) its length (2) its thickness (3) its shape (4) nature of the material

Answer: (4) nature of the material

The Property of the conductor which resists the flow of electric current is called resistivity. Resistance for a particular material is unique. Resistance is directly proportional to the length of conductor and inversely proportional to current flow.

Different metals will have different melting points, boiling points, and so on, and they will have different properties that influence the resistivity of a material relative to each other.
