Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Energy
1. Concept:

An electron-volt is a localized unit representing the kinetic energy an electron gains when accelerated through a one-volt field.

2. Formula:

$$ W = q \Delta V $$

3. Solution:

  • Charge \( \times \) Voltage = Joules.


  • Since an electron-volt directly maps to \( 1.6 \times 10^{-19} \text{ Joules} \), it is inherently a measurement of Energy.


4. Why other options are incorrect:

Charge is Coulombs. Current is Amperes. Power is Watts (Energy over time). The presence of the word "Volt" often misleads students into associating it with potential rather than energy.

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.
