If the p - n junction diode is unbiased,

Options

  1. An-type side has lower potential than p-type side.
  2. Bn-type side has same potential as p-type side.
  3. CAn electric field is established at the junction such that n side is at positive voltage relative to p -side.
  4. DThe potential across the junction is such that p -side is at positive voltage relative to n -side

Correct answer

C. An electric field is established at the junction such that n side is at positive voltage relative to p -side.

Step-by-step solution

n-type side has lower potential than p-type side: This is correct. The built-in electric field causes the p -side to have a higher potential than the n -side.
