Semiconductor Electronics Materials Devices And Simple Circuits Ques 1
1. In a $p-n$ junction
[2002]
(a) The potential of the $p$ and $n$-sides becomes higher alternately
(b) The $p$-side is at higher electrical potential than the $\mathrm{n}$ side
(c) The $n$-side is at higher electrical potential than the $p$-side
(d) Both the $p$ and $n$-sides are at the same potential
Show Answer
Answer:
Correct Answer: 1.(b)
Solution: (b) For conduction, $p-n$ junction must be forward biased. For conduction $p$-side should be connected to higher potential and $n$-side to lower potential.
