MCQ
The solids which have the negative temperature coefficient of resistance are :
- ✓Insulators and semiconductors
- Bmetals
- Cinsulators only
- Dsemiconductors only
✓
Answer
Correct option: A.
Insulators and semiconductors
a
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.
