If the forward voltage in a diode is increased, then the width of the depletion region

Options

  1. Aincreases
  2. Bdecreases
  3. Cfluctuates
  4. Dno change

Correct answer

B. decreases

Step-by-step solution

When forward voltage in a diode is increased, then it opposes the potential barrier. Due to it, the potential barrier is considerably reduced and hence depletion region decreases.
