In forward biasing of a p-n junction,

Options

  1. Aelectrons move from lower to higher energy level
  2. Belectrons move from higher to lower energy level
  3. Choles in valence band move from higher energy level to lower energy level
  4. DNone of the above

Correct answer

B. electrons move from higher to lower energy level

Step-by-step solution

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.
