The graph of potential barrier versus width of depletion region for an unbiased diode is shown in A. In comparison to A, graphs B and C are obtained after biasing the diode in different ways. Identify the type of biasing in B & C and justify your answer.                                        (3) marks



Explanation:

 B : reverse biased                                             12

C: forward biased                                               12
