Concept:A full-wave rectifier inverts the negative half-cycles of an AC input into positive pulses, producing continuous, unidirectional output pulses across the load.
Formula:$$v_{\text{out}}(t) = |V_m \sin(\omega t)| \quad \text{for all } t$$
Solution:- The output waveform contains contiguous positive sinusoidal pulses with no dead-time gaps between half-cycles.
- This continuous pulsating DC output is characteristic of full-wave rectifiers (both bridge and center-tapped topologies).
Why other options are incorrect:- Option B: Half-wave rectifiers have zero-voltage gaps between alternate pulses.
- Option C: High-pass RC filters produce differentiated AC spikes centered around zero volts.
- Option D: Differentiators output cosine waves from sine inputs, alternating between positive and negative polarities.
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.
