A zener diode is used for

A)  rectification                      

B)  modulation

C)  detection                          

D) voltage regulation

Correct Answer: D

Solution :

                Zener diode is a highly doped p-n junction which is not damaged by high reverse current. It can operate continuously without being damaged in the region of reverse breakdown voltage. In the forward bias, the zener diode acts as ordinary diode. It can be used as, voltage regulator
