Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Potential
1. Concept:

A capacitor functions by separating charges, doing work against the electric field, and holding those separated charges static until a circuit is completed.

2. Formula:

$$ U_E = \frac{1}{2} C V^2 $$

3. Solution:

  • Because the charges are held stationary (static) on the opposing plates, the energy is strictly stored as Electrical Potential Energy inside the electric field.


4. Why other options are incorrect:

Kinetic energy involves active motion (like current flowing). Thermal and Light energy describe forms of energy dissipation (like a resistor or bulb), not storage.

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.
