In a p-n junction (a) high potential at n side and low potential at p side (b) high potential at P side and low potential at n side (c) p and n both are at same potential (d) undetermined.

Answer: (b). At the junction, n side keeps positive donor ions and p side keeps negative acceptor ions. So the n side is at higher potential and the p side at lower potential. This matches option (a).
