In an unbiased junction

• A

  Potential at is more than that at
• Correct answer
  B

  Potential at is less than that at
• C

  Potential at is equal to that at
• D

  Potential at is +ve and that at is -ve

Solution

Graph between potential and distance in a junction diode is given by

$\therefore$ potential at is less than that at .

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