In forward biased if the p−n junctions diode is forward biased, then width of potential barrier in p−n junction diode :
A
Remain constant
B
increase
C
Decrease
D
none of these
Answer
Decrease
Explanation
Solution
In forward bias the terminal of the same polarity are connected between the diode and the supply. Hence by repulsion excess number of holes or electron come out and width of potential barrier can be decreased.
