Question:
The temperature coefficient of a metal is ___ and that of a semiconductor is ___ respectively
The temperature coefficient of a metal is ___ and that of a semiconductor is ___ respectively
Show Hint
Metals: +ve coefficient, Semiconductors: –ve coefficient.
Updated On: Jul 2, 2026
- \(+ve, -ve\)
- \(+ve, +ve\)
- \(-ve, +ve\)
- \(-ve, -ve\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Temperature coefficient indicates how resistance changes with temperature.
Step 1: Metals behavior Resistance increases with temperature.
Step 2: Reason Increased lattice vibrations → more collisions.
Step 3: Sign of coefficient Positive for metals.
Step 4: Semiconductor behavior Resistance decreases with temperature.
Step 5: Conclusion \[ \boxed{+ve, -ve} \]
Final Answer: \[ \boxed{(A)} \]
