The energy band occupied by the valence electrons is called___________________?
Correct answer: B. Valence band
- A. Energy state
- B. Valence band
- C. ve energy state
- D. conduction band
Explanation
The valence band is the allowed energy band containing the valence electrons of a solid. The conduction band, the likely mistaken choice, contains electrons that have gained enough energy to move through the material and conduct current.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
