Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Ampere
Concept:

The International System of Units (SI) defines exactly 7 base quantities.

Solution:

  • Electric current is one of the fundamental SI base quantities.


  • Its assigned standard SI unit is universally the Ampere.


Why other options are incorrect:

  • Opt B: Coulomb is the SI derived unit of charge.


  • Opt C: Ohm is the unit of resistance.


  • Opt D: Ohm-meter is the unit of resistivity.

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.
