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

Then the output signal across R_{L} will be

 

  • Option 1)

  • Option 2)

  • Option 3)

  • Option 4)

 

Answers (1)

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 

\rightarrow \infty Reverse

 

 For - ve applied voltage the diode is in reverse biased mode and hence there is no current output across R_{L}=0

If + 5V is applied, diode is is in forward biased mode and hence offer no resistance. 

Output voltage = 5V

Correct option is 1.

 


Option 1)

This is the correct option.

Option 2)

This is an incorrect option.

Option 3)

This is an incorrect option.

Option 4)

This is an incorrect option.
