A p-n junction diode in a circuit is in reverse bias but not under breakdown condition. As compared to the p-n junction diode in a forward bias,

• Correct answer
  A

  the depletion layer width increases.
• B

  the barrier potential decreases.
• C

  the current enhances significantly across the junction.
• D

  the electric field across the junction changes sign.

Hence, the correct answer is option: 'A'.
