When junction diode is forward biased, then
the depletion region is reduced and barrier height is increased
the depletion region is widened and barrier height is reduced
both the depletion region and barrier height are reduced
both the depletion region and barrier height are increased
As we have learnt,
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
When p-n junction is forward biased, the depletion religion and barrier height are reduced.
Option 1)
the depletion region is reduced and barrier height is increased
Option 2)
the depletion region is widened and barrier height is reduced
Option 3)
both the depletion region and barrier height are reduced
Option 4)
both the depletion region and barrier height are increased
