Question

When forward bias is applied to a P-N junction, then what happens to the potential barrier$V_{B}$, and the width of charge depleted region x.

• A. $V_{B}$ increases, x decreases
• B. $V_{B}$ decreases, x increases
• C. $V_{B}$ increases, x increases
• D. $V_{B}$ decreases, x decreases

Answer 1

Answer: (D)

$V_{B}$ decreases, x decreases

Answer 2

In forward biasing both V_B and x decreases.
