Propolis Cognitive Error Autopsy

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

Capacitors physically store electrical potential energy in the space directly between their conducting plates.

2. Formula:

$$ U = \frac{1}{2} \epsilon_0 E^2 (A \cdot d) $$

3. Solution:

  • The energy density equation proves that the energy fundamentally resides within the electric field (often referred to as 'electric intensity' in older nomenclature) that bridges the gap between the isolated charges.


4. Why other options are incorrect:

Magnetic energy is strictly stored by Inductors (via current flow). Kinetic energy pertains to motion. Gravitational energy is mass-dependent, not charge-dependent.

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.
