If in a p-n junction, a square input signal of 10 V is applied, as shown,

then the output across RL will be:

  • Option 1)

  • Option 2)

  • Option 3)

  • Option 4)

As we learnt in

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 

ightarrow infty Reverse


Diode will pass the current only when it is forward biased. Hence output will be obtained when voltage is positive that is it lies between 0 - 5 V.

Option 1)

This option is incorrect

Option 2)

This option is correct

Option 3)

This option is incorrect

Option 4)

This option is incorrect
