In forward biasing of a \(p-n\) junction,
- A electrons move from lower to higher energy level
- B electrons move from higher to lower energy level
- C holes in valence band move from higher energy level to lower energy level
- D None of the above
Answer & Solution
Correct Answer
(B) electrons move from higher to lower energy level
Step-by-step Solution
Detailed explanation
When a \(p-n\) junction is connected in forward bias, an electric field exists which causes electrons to move from \(n\) to \(p\)-side (forward current). As electrons are in conduction band and holes are in valence band, thus electrons move from higher to lower energy levels.
