Question

What happens during regulation action of a zener diode?

• A. The current through the series resistance $abla( R_{S} )$ changes.
• B. The resistance offered by the zener changes
• C. The zener resistance is constant.
• D. Both (1) and (2)

Answer 1

Answer: (D)

Both (1) and (2)

Answer 2

: 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.
