Q. $p - n$ junction is said to be forward biased, when
A) The positive pole of the battery is joined to the $p$-semiconductor and negative pole to the $n$-semiconductor
B) The positive pole of the battery is joined to the $n$-semiconductor and negative pole to the $n$-semiconductor and $p$-semiconductor
C) The positive pole of the battery is connected to $n$-semiconductor and $p$-semiconductor
D) A mechanical force is applied in the forward direction
Explanation
(a) For forward biasing of $p - n$ junction, the positive terminal of external battery is to be connected to $p$-semiconductor and negative terminal of battery to the $n$-semiconductor.
