Question

28.
In a p-n junction without any external voltage
1 P and n both are at same potential
2) high potential at n-side and low potential at p-side
3) high potential at p-side and low potential at n-side
4) low potential at n-side and zero potential at p-side​

Answer 1

Hey mate....

Here is your answer....

high potential at n side and low potential at p side

(option 2)

This is because in the junction an electric field is developed from n to p.

Therefore by convention n side has higher potential relative to p.
