A Zener regulator _____________ in the power supply?
Correct answer: B. Decreases the ripple
- A. Increases the ripple
- B. Decreases the ripple
- C. Neither increases nor decreases the ripple
- D. Data insufficient
Explanation
A Zener regulator holds the output voltage nearly constant, so variations in the rectifier output appear less at the load as ripple. Therefore, it decreases the ripple voltage.
