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


(a) the potential is the same everywhere

(b) the p-type side is at a higher potential than the n-type side

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

(d) there is ane electric field at the junction directed from the p-type side to the n-type side

 

Best Answer

At junction a potential barrier/depletion layer is formed as shown, 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.
