In a P -N junction |
the potential of P & N sides becomes higher alternately the P side is at higher electrical potential than N side. the N side is at higher electric potential than P side. both P & N sides are at same potential. |
the P side is at higher electrical potential than N side. |
[Hint : For easy flow of current the P side must be connected to +ive terminal of battery i.e., it is connected to higher potential in comparison to N. This connection is called forward biased. In this case the input resistance is very low. In reverse – biased, the P-side is connected to – ive terminal & N side to (+ive) terminal to battery. In this case input resistance is very high. |
