Of the diodes shown in the following diagrams, which one is reverse biased?                             

A)

B)

C)

D)

Correct Answer: C

Solution :

When a battery is connected to junction diode with p-side connected to negative terminal and n-side to the positive terminal, the junction diode is reverse biased. The circuit shown in figure can be redrawn as In the option (c), the p-end of the diode is connected to negative terminal of the battery, so the diode has been reverse biased.
