                For conduction in a p-n junction, the biasing is:

A)                                                                                                            high potential on n-side and low potential on p-side

B)                 high potential on p-side and low potential on n-side                                    

C)                 same potential on both p and n-sides

D)                 undetermined

Correct Answer: B

Solution :

                For conduction in a p-n junction, it should be forward biased. For this p-side must be connected to positive terminal (higher potential) and n-side must be connected to negative terminal (lower potential). Figure below shows the p-n junction in a conducting state (forward biased condition)
