Question

If the forward bias voltage in a $p-n$ junction diode is decreased, the length of depletion region will

• A. Increase
• B. Decrease
• C. Not change
• D. Initially increase and then decrease

Answer 1

Answer: (A)

Due to application of forward biased voltage, the length of depletion region decreases and vice versa. Thus, decrease in forward biased voltage increases the length of depletion region.
