A forward biased diode is:

A)  

B)         

C)         

D)         

Correct Answer: D

Solution :

The \[p-n\] junction diode is as shown: If \[p-\]side of \[p-n\] junction diode is given more positive potential than\[n-\]side, then it is forward biased. In option (d),\[p-\]side is at\[0V\]and\[n-\]side at\[-2V\], so\[p\]is at higher potential. Hence, it is forward biased.
