Suppose an unregulated D.C. input voltage `V_(1)` is applied to a Zener diode having breakdown voltage `(V_(z))`. Then the breakdown condition for the diode to work as voltage regulator is

A

`V_(I)ltV_(Z)`

B

`V_(I)=V_(Z)`

C

`V_(I)gtV_(Z)`

D

`V_(I)=sqrt(V_Z)`

Text Solution

Verified by Experts

The correct Answer is:
C
For the breakdown condition of the Zener diode, the applied voltage `V_(I)gtV_(Z).` In that case, for a wide range of values, the current will change but the voltage remains constant.
