Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Semiconductor
Concept:

Diodes are manufactured from materials whose electrical properties lie between those of good conductors and insulators.

Solution:

  • A P-N junction diode is forged by doping Silicon or Germanium to create P-type and N-type regions.


  • Silicon and Germanium are fundamentally semiconductor materials.


  • Because their conductivity can be precisely controlled by doping and biasing, they make perfect rectifying devices.


Why other options are incorrect:

  • Perfect conducting: A short circuit, cannot rectify.


  • Insulating / Perfect insulating: An open circuit, current could never flow.

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.
