Which rectifier circuit uses two diodes and a center-tapped transformer?

A full-wave rectifier.

  1. Full-wave bridge
  2. Half-wave
  3. Full-wave ✔

Why: A center-tapped transformer lets two diodes take turns on each half of the AC cycle. That is a full-wave rectifier. A half-wave circuit needs only one diode.

Huh, didn't know that: An unfiltered full-wave rectifier makes DC pulses at twice the frequency of the AC input.
