For aluminium, as compared to copper, all the following factors have higher values except:
Correct answer: B. electrical conductivity
- A. specific volume
- B. electrical conductivity
- C. co-efficient of linear expansion
- D. resistance per unit length for same cross-section
Explanation
Aluminium has lower electrical conductivity than copper, so conductivity is the exception. It has higher specific volume, thermal expansion coefficient, and resistance for the same cross-sectional area.
