If the following input signal is sent through a PN-junction diode, then the output signal across \[{{R}_{L}}\] will be

A)

B)

C)

D)

Correct Answer: C

Solution :

[c] When input voltage is \[-10\text{ }V,\] the diode is reverse biased and no output is obtained. On the other hand, when input is \[+10\text{ }V,\] the diode is forward biased and output is obtained which is \[+10\text{ }V,\] Therefore the output is of the form as show in the following figure.
