MCQ
The energy gap in a conductor at room temperature is ________ .
- AGreater than that in a semiconductor.
- BLess than that in a insulator.
- CGreater than that in a insulator.
- DBoth (a) and (b) are true.
✓
Answer
- Less than that in a insulator.
Explanation:
The energy band gap is the energy difference between 2 bands i.e. valence band and the conduction band. In case of conductors, energy band gap is very small almost overlapping whereas, in case of insulators, the band gap is ∼6 eV. So. band gap of conductors is less than insulators.
