In a p- n junction diode not connected to any circuit,

the potential is the same everywhere

the p-type side is at a higher potential than the n-type side.

there is an electric field at the junction directed from the n-type side to the p-type side.

there is an electric field at the junction directed from the p-type side to the n-type side.

Text Solution

Verified by Experts

The correct Answer is:

In a p-n junction diode, a depletion layer or a potential barrier is formed.
The n-side of depletion layer is at higher potential, and p-side is at lower potential.
