Question:

The graph given below represents the I – V characteristics of a Zener diode. Which part of the characteristics curve is most relevant for its operation as a voltage regulator:

Options:

ab

bc

cd

de

Correct Answer:

cd

Explanation:

If the reverse bias is greater than the $V_x$ there is breakdown condition. In breakdown region i.e., $V_i>V_x$, for a long range of load, $(R_L)$.
