MCQ
Materials which allow only larger currents to flow through them are:
- AInsulators
- BSemi-conductors
- CConductors
- DAlloys
✓
Answer
- Semi-conductors
Explanation:
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.
