The graph shown in Fig. represents the I-V characteristics of a zener diode. Which part of the characteristics curve is most relevent for its operation as a voltage regular?

A

ab

B

bc

C

cd

D

de

Text Solution

Verified by Experts

The correct Answer is:
D
If the reverse bias voltage is greater than the `V_(z),` then breakdown condition arises. In breakdown region i.e., `V_(i)gtV_(z),` for a long range of load `(R_(L)),` the voltage remains the same though the current may be large.
