Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Period
Concept:

This is a definition-based question covering basic parameters of alternating current theory.

Solution:

The Time Period (or simply period, \( T \)) is defined as the precise duration in seconds required for an alternating signal to complete one full cycle of positive and negative values.

Why other options are incorrect:

  • Cycle is the physical repeating unit itself, not its duration.


  • Instantaneous value is the value of voltage or current at any specific split second of 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.
