What happens to the width of the depletion layer in ap.n junction diode when it is
1) forward-biased and
2) reverse -biased ?

What are 1) forward bias and 2) reverse - bias?

Consider the following statement A and B and identify the correct choice of the given answer. A. The width of the depletion layer in a p-n junction diode increases in forward bias. B. In a intrinsic semiconductor the fermi energy level is exactly in the middle of the forbidden energy gap.
