Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Electric potential
1. Concept:

This is the fundamental macroscopic definition of voltage (electric potential).

2. Formula:

$$ V = \frac{W}{q} $$

3. Solution:

  • By defining Joules of work (W) required to move a specific Coulomb count (q), we arrive at Joules/Coulomb. This ratio defines the Volt, which measures Electric Potential.


4. Why other options are incorrect:

Electric field is force per unit charge (Newtons per Coulomb), entirely lacking the distance metric required for 'work'.

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.
