Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Steady current
Concept:

By definition, Ideal DC from a stable source provides a constant, unchanging flow over time.

Solution:

  • A current that flows in a singular direction with a perfectly constant magnitude (intensity) is referred to as a Steady current.


Why other options are incorrect:

  • Opt A: Eddy currents are localized circular loops induced by changing magnetic fields.


  • Opt B: Surge current implies a massive, momentary spike.


  • Opt C: Leakage implies a gradual, unwanted escape of charge across a dielectric over time.

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.
