In a 
‐junction diode not connected to any circuit [2015]
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 
− − side at higher potential and 
− − side at lower potential. Therefore there is an electric field at the junction directed from the 
− − side to 
− − side
