Question

When the voltage applied across a reverse biased p-n junction diode is increased, then the diffusion current

• A. increases
• B. decreases
• C. first increases and then decreases
• D. remains constant

Hint:

In reverse biased p-n junction diodes, the diffusion current increases with applied voltage until a breakdown occurs.

Answer 1

The Correct Option is A

In a reverse biased p-n junction diode, the diffusion current increases as the voltage is increased because the increased voltage leads to an increased movement of charge carriers across the junction.
