In a Zener voltage regulator, the changes in load current produce changes in _________________?
Correct answer: A. Zener current
- A. Zener current
- B. Zener voltage
- C. Zener voltage as well as Zener current
- D. None of the above
Explanation
In the regulation region, the Zener voltage remains nearly constant, so a change in load current is mainly balanced by an opposite change in Zener current. This is the shunt regulator’s basic operating principle.
