Question

What happens during regualtion action of a Zener diode?
A. The current through the series resistance `(R_S)` changes
B. The resistance offered by the Zener changes
C. The Zener resistance is constant.
D. Both (a) and (b)

Answer 1

Correct Answer - D
During regulation action of a Zener diode, the current through the series resistance changes and resistance offered by the Zener changes. The current through the Zener changes but the voltage across the Zener remains constant.
