Which rectifier uses both halves of the input waveform to produce DC?

• A. Half-wave Rectifier
• B. Germanium/Silicon
• C. Full-wave Rectifier
• D. Toggle Switch

Answer: (C)

Rectification that uses both halves of the input waveform to create DC is achieved by a full-wave rectifier. In this configuration, current is harnessed from both the positive and negative halves of the AC cycle and redirected so the output always flows in the same direction through the load. This can be done with a center-tapped transformer and two diodes or with a bridge of four diodes. As a result, the output is pulsating DC at twice the input frequency, which can then be smoothed with a capacitor if a steadier DC is needed. The other options don’t fit: a half-wave rectifier uses only one half of the AC waveform, discarding the other half; a material like germanium or silicon refers to diode material rather than a rectifier configuration; a toggle switch is simply a mechanical on/off device and does not rectify AC.
