Q. 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
Explanation
(d) In forward biasing both $V_{B}$ and $x$ decreases
