Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: opposition to the motion of charges
Concept:

The fundamental definition of electrical resistance.

Solution:

  • As electrons drift through a lattice, they violently collide with the atomic structure of the material.


  • These collisions inherently restrict and slow down the steady flow of the electrons.


  • Therefore, Resistance is formally defined as the opposition to the motion of charges.


Why other options are incorrect:

  • Opt A & C: Define current.


  • Opt B: Defines the potential pushing force.

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.
