What portion of the AC cycle is converted to DC by a full-wave rectifier?
- A.90 degrees
- B.180 degrees
- C.270 degrees
- D.360 degrees (correct answer)
WhyA full-wave rectifier converts the entire 360-degree AC cycle to DC. A full-wave rectifier reshapes both halves of the AC cycle into usable DC pulses, converting the entire 360-degree cycle, answer D. It isn't limited to only 90, 180, or 270 degrees of the waveform, that partial conversion describes a half-wave rectifier instead.
