When p-n junction diode is forward biased, then

  • 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

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 

\rightarrow \infty 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
