Topic: Material Science
Pure Metals generally have
- A. High Conductivity and Low temperature coefficient
- B. High Conductivity and High temperature coefficient
- C. Low Conductivity and zero temperature coefficient
- D. Low Conductivity and High temperature coefficient
Answer: B. High Conductivity and High temperature coefficient
Explanation: Pure metals have high electrical conductivity due to a large number of free electrons. They also have a high positive temperature coefficient of resistance because increased temperature significantly increases lattice scattering.
