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
We know that if the reverse bias is greater than the `V_(z)`, a breakdown condition is obtained, showing a sudden rise in the reverse current. In breakdown region, `V_(i)gtV_(z)`, for a long range of load `(R_(L))`, the voltage across `R_(L)` remains the same throgh the current may change. Therefore, portion de of the characteristics curve is relevant for the operation of zener diode as voltage regulator.
