What happens during regualtion action of a Zener diode?

Options

A. The current and voltage across the Zener remains fixed
B. The current through the series Resistance `(R_(s))` changes
C. The Zener resistance is constant
D. The resistance offered by the Zener change.

Answer

A, D

Explanation

During regulation action of a Zener diode, the current through the `R_(s)` changes and reistance offered by the Zener changes. The current through the Zener change but the voltage across the Zener remains constant.
