Electrical resistivity of a given metallic wire depends upon:
Electrical resistivity of a given metallic wire depends upon:
- A. its length
- B. its thickness
- C. its shape
- D. nature of the material
Step-by-step solution
Electrical resistivity is an intrinsic property of a material, meaning it depends only on the material's composition and structure, not on its physical dimensions like length, thickness, or shape. Therefore, the correct answer is D.
