Which of the following statements are wrong w.r.t the specific resistance of wir
Which of the following statements are wrong w.r.t the specific resistance of wire? This question has multiple correct options
- A. It varies with its length
- B. It varies with its cross-section
- C. It varies with its mass
- D. It varies with nature of material
Step-by-step solution
Specific resistance (resistivity) is an intrinsic property of a material, independent of the wire's length, cross-sectional area, or mass. It depends only on the nature of the material and temperature. Therefore, statement A is incorrect.
