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

• A

   ${\mathrm{V}}_{\mathrm{B}}$ increases, x decreases

• B

  ${\mathrm{V}}_{\mathrm{B}}$decreases, .x increases

• C

  ${\mathrm{V}}_{\mathrm{B}}$increases, x increases

• D

  ${\mathrm{V}}_{\mathrm{B}}$decreases, x decreases
