Question

When forward bias is applied to a P-N junction, then what happens to the potential barrier VB, and the width of charge depleted region x ? (A) VB increases, x decreases (B) VB decreases, x increases (C) VB increases, x increases (D) VB decreases, x decreases

In forward biasing, both VB and x decrease.

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 $x ?$

$V_{B}$ increases, $x$ decreases

$V_{B}$ decreases, $x$ increases

$V_{B}$ increases, $x$ increases

$V_{B}$ decreases, $x$ decreases

In forward biasing, both $V_{B}$ and $x$ decrease.

Q. When forward bias is applied to a P−N junction, then what happens to the potential barrier VB​, and the width of charge depleted region x?

VB​ increases, x decreases

VB​ decreases, x increases

VB​ increases, x increases

VB​ decreases, x decreases
