In forward bias, the width of potential barrier in a P-N junction diode
Increases
Decreases
Remains constant
First increases then decreases
P -N junction as diode -
It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.
- wherein
R = 0, Forward
R Reverse
In forward bias, The width of potential barrier decreases and hence flow of current becomes high
