When a $P-N$ junction is in forward bias,what happens to the depletion region and the potential barrier?

  • A
    The depletion region decreases and the potential barrier height increases.
  • B
    The depletion region widens and the potential barrier height decreases.
  • C
    Both the depletion region and the potential barrier height decrease.
  • D
    Both the depletion region and the potential barrier height increase.

Two statements are given below:
$A$. When the forward bias voltage across a $p-n$ junction diode increases above a certain threshold voltage, the diode current increases significantly.
$B$. This current is called reverse saturation current.
Choose the correct answer from the options given below:

Consider a $p-n$ junction as a capacitor, formed with $p$ and $n$-materials acting as thin metal electrodes and depletion layer width acting as separation between them. Basing on this, assume that an $n-p-n$ transistor is working as an amplifier in $CE$ configuration. If $C_1$ and $C_2$ are the base-emitter and collector-emitter junction capacitances, then :

The change in current through a junction diode is $12 \, mA$ when the forward bias voltage is changed by $0.6 \, V$. The dynamic resistance is
