Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Ohm's Law
Concept:

The linear relationship between current and voltage under constant physical conditions is a fundamental principle of basic circuits.

Solution:

  • The statement "\( V \propto I \) at constant temperature" is the exact textbook definition of Ohm's Law.


Why other options are incorrect:

  • Opt A: Joule's Law deals with heat dissipation (\(P = I^2R\)).


  • Opt B & D: Gauss's and Ampere's laws deal with electromagnetics and flux, not basic circuit resistance.

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.
