MCQ
Materials which allow only larger currents to flow through them are:
- AInsulators
- ✓Semi$-$conductors
- CConductors
- DAlloys
✓
Answer
Correct option: B.
Semi$-$conductors
Semiconductors in their natural state are poor conductors because a current requires the flow of electrons, and semiconductors have their valence band filled, preventing the entry flow of new electrons.
Thus semi$-$conductors allows a large current to pass through them.
