Marine Electrical Systems USCG Question #425 (Set 15)

Which section of the circuit shown in the illustration smoothes out highest degree of pulsations? Illustration EL-0085

Official USCG Answer & Rule Citation

Correct Answer: Option C — C

Section C typically houses the filter capacitor and LC network within a regulated power supply. According to IEEE 45 principles, this stage effectively attenuates remaining AC ripples, smoothing out high-degree pulsations to deliver stable DC for sensitive shipboard electronics.
