Some electrons move from one level to another in_.
Correct answer: A. Semi-conductor
- A. Semi-conductor
- B. Insulator
- C. Conductors
- D. None of these
Explanation
Semiconductors have a smaller band gap than insulators. They can conduct electricity better than insulators but not as well as conductors. At low temperatures or when energy is added, electrons can jump from the valence band to the conduction band, allowing for some conductivity.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
