Official Correct Choice:
Option C: Four diodes connected in bridge type arrangements
Concept:

A full-wave bridge rectifier is a highly efficient topology that rectifies the full AC wave without needing a specialized center-tapped transformer.

Solution:

  • The "bridge" configuration explicitly consists of a diamond-like arrangement of diodes.


  • To ensure that both the positive and negative halves of the AC cycle are directed identically through the load, precisely four diodes are required.


  • During any half cycle, two diodes conduct while the other two block.


Why other options are incorrect:

  • You cannot build a functional bridge topology with 1, 2, or 3 diodes; they would result in either half-wave rectification, no rectification, or a dead short.

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.
