Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 57
58. p-n junction is said to be forward biased, when
[1988]
(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 $p$-semiconductor joined to negative pole of the battery
(c) the positive pole of the battery is connected to $n$-semiconductor and $p$-semiconductor is connected to the positive pole of the battery
(d) a mechanical force is applied in the forward direction
Show Answer
Answer:
Correct Answer: 58. (a)
Solution:
- (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.
