Question

For which of the following conditions, the width of the depletion region in a p-n junction diode decreases ?

• A. Reverse bias
• B. Forward bias
• C. Both forward bias and reverse bias
• D. Decreasing the doping concentration

Answer 1

The correct option is B Forward bias

In forward bias width of depletion region of p-n junction diode decreases and in reverse bias width of depletion region of p-n junction diode increases. On decreasing the doping concentration, depletion width increases
