NEET · Physics · STD 12 - 14. Semicondutor electronics
The solids which have the negative temperature coefficient of resistance are :
- A Insulators and semiconductors
- B metals
- C insulators only
- D semiconductors only
Answer & Solution
Correct Answer
(A) Insulators and semiconductors
Step-by-step Solution
Detailed explanation
The negative temperature coefficient of the resistance is only present in the insulators or the semiconductors. In these, the resistance decreases with increase in temperature.
