Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Rectifier
Concept:

Power supply design heavily relies on specific circuits to convert alternating currents to direct currents.

Solution:

  • The dedicated electronic circuit constructed (usually with diodes) to convert bidirectional AC into unidirectional DC is known universally as a Rectifier.


Why other options are incorrect:

  • Amplifier: Boosts the power of an input signal.


  • Detector: Extracts information from a modulated radio wave.


  • Emitter: A physical terminal on a bipolar junction transistor, not a circuit type.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
