Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Conventional current
Concept:

Historically, electric current was defined before the discovery of the electron.

Solution:

  • The flow of current from a higher potential (positive terminal) to a lower potential (negative terminal) mimics the theoretical flow of positive charges.


  • This standardized model is universally known as Conventional current.


Why other options are incorrect:

  • Opt A: Electronic current flows from lower potential (negative) to higher potential (positive).


  • Opt B & C: Magnetic lines aren't currents; "Electric current" is a general term that doesn't specify directionality based on positive charge 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.
