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

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
For negative potential, the diode becomes reverse biased whereas for positive potential diode is forward biased.
For `V_(i) lt 0`, the diode is reverse biased and hence offer infinite resistance, so circuit would be like as shown in Figure and `V_(0)=0`.

For `V_(i) gt 0`, the diode is forward biased and circuit would be as shown in Fig. (3) and `V_(0)=V_(i)`.
