Official Correct Choice:
Option B: Charge
Concept:

Charge is fundamentally defined as the product of current flow over time.

Formula:

$$ Q = I \times t $$

Solution:

  • Current \( I \) is measured in Amperes.


  • Time \( t \) is measured in Seconds.


  • Multiplying them yields Ampere \(\times\) second, which is the definition of the Coulomb, the standard unit of Charge.


Why other options are incorrect:

  • Opt A: Power is Joules/second (Watts).


  • Opt C: Potential difference is Joules/Coulomb (Volts).


  • Opt D: Current is purely Amperes.

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.
