Question

2. With forward biased mode, the p-n junction diode
a) is one in which width of depletion layer increases?
b) is one in which potential barrier increases.
c) Acts as closed switch.
d) Acts as open switch.​

Answer 1

Answer:

In a forward biased mode, p-n junction has lesser potential barrier and width of depletion layer also decreases.

Almost all the current passes through it and hence it acts as a close switch.

Hence, answer is option-(C).
