Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Diode
Concept:

A rectifier circuit necessitates a component that restricts current flow to a single direction.

Solution:

  • The fundamental semiconductor device that exhibits this unidirectional current property is the P-N junction diode.


  • By blocking the negative cycle of AC and passing the positive cycle, the diode actively "rectifies" the signal.


Why other options are incorrect:

  • Transformer: Changes voltage amplitude but outputs AC.


  • Transistor: Acts as a switch or amplifier.


  • Inductor: A passive filter component, incapable of rectification.

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.
