In a 
-junction diode, not connected to any circuit,
A
the potential is the same everywhere
B
the 
-type is a higher potential than the 
-type side
-type is a higher potential than the -type side C
there is an electric field at the junction directed from the 
-type side to the 
-type side
-type side to the -type side D
there is an electric field at the junction directed from the 
-type side to the 
-type side
-type side to the -type side
Text Solution
Verified by ExpertsThe correct answer is:
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 
-side to 
-side
