A circuit used when the desired dc output is less than the output of the power supply is a
A) zener regulator.
B) high-pass filter.
C) low-pass filter.
D) bridge rectifier.

Question

Quizplus · Accepted Answer

A zener regulator is designed to maintain a constant voltage output even if the input voltage varies. It is commonly used when the desired output voltage is less than the input voltage. Hence, option A is the correct choice. Options B, C, and D are not applicable in this scenario. A high-pass filter allows high-frequency signals to pass through and attenuates low-frequency signals. A low-pass filter allows low-frequency signals to pass through and attenuates high-frequency signals. A bridge rectifier is used to convert AC voltage to DC voltage. None of these circuits address the issue of obtaining a lower output voltage than the input voltage.
