*Question G7A06:
What portion of the AC cycle is converted to DC by a full-wave rectifier?*  

*Correct Answer is  D: 360 degrees*  

### AI Response: (may contain errors)  

A full-wave rectifier converts the entire AC cycle into DC. Let's break down why the correct answer is 360 degrees:

1. **Why the correct answer is correct (360 degrees):**
   - A full-wave rectifier inverts the negative half of the AC waveform, effectively using both the positive and negative halves of the cycle. This means it converts the entire 360 degrees of the AC cycle into DC. 

2. **Why the other choices are incorrect:**
   - **90 degrees (Choice A):** This would imply that only a quarter of the AC cycle is converted to DC, which is not the case for a full-wave rectifier.
   - **180 degrees (Choice B):** This would be true for a half-wave rectifier, which only converts one half (either positive or negative) of the AC cycle to DC. However, a full-wave rectifier uses both halves.
   - **270 degrees (Choice C):** This suggests that three-quarters of the cycle is converted, which is incorrect for a full-wave rectifier.

3. **Useful concepts:**
   - **Full-Wave Rectification:** Utilizes both halves of the AC waveform, effectively doubling the frequency of the output DC compared to a half-wave rectifier.
   - **AC Cycle:** A complete cycle of AC is 360 degrees, representing one full sine wave oscillation.

In summary, a full-wave rectifier converts the entire 360 degrees of the AC cycle into DC, making the correct answer 360 degrees.
