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  \rightarrow \infty Reverse

 

 

When input is -5V, then diode is reverse biased and hence output is zero

When input is +5V, then output is also +5V

 

 


Option 1)

Option 2)

Option 3)

Option 4)
