Q. Application of a forward bias to a $p$-$n$ junction
A) Increase the number of donors on the $n$-side
B) Increase the electric field in the depletion zone
C) Increase the potential difference across (the depletion zone)
D) Widens the depletion zone
Explanation
(a) When $p$-side of junction diode is connected to positive of battery and $n$-side to the negative, then junction diode is forward biased.

In this condition, more number of electrons enter in $n$-side from battery theryby increasing the number of donors on $n$-side.
