MCQ

In a $PN-$ junction diode not connected to any circuit

A
The potential is the same everywhere
B
The $ P-$ type is 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
D
There is an electric field at the junction directed from the $P-$ type side to the $N-$type side

✓

Answer

Correct option: C.

There is an electric field at the junction directed from the $N-$ type side to the $ P- $ type side

c
(c)At junction a potential barrier/depletion layer is formed, with $N-$ side at higher potential and $ P- $ side at lower potential. Therefore there is an electric field at the junction directed from the $N-$ side to $P-$ side
