*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 both halves of the AC cycle into DC. 

1. **Correct Answer Explanation (360 degrees)**:
   - A full-wave rectifier takes the entire AC waveform and converts it to DC. This means that it utilizes both the positive and negative halves of the AC cycle. Since one complete cycle of AC is 360 degrees, the full-wave rectifier effectively converts the entire 360 degrees of the AC waveform into DC.

2. **Incorrect Choices Explanation**:
   - **A: 90 degrees**: This choice represents only a quarter of the AC cycle. A full-wave rectifier does not only convert a small portion; it uses the entire cycle.
   - **B: 180 degrees**: This choice represents half of the AC cycle. While a half-wave rectifier only uses one half (either positive or negative), a full-wave rectifier uses both halves, thus converting the full 360 degrees.
   - **C: 270 degrees**: This choice represents three-quarters of the AC cycle. Again, this is not applicable to a full-wave rectifier, which converts the entire cycle.

3. **Useful Rule of Thumb**:
   - Remember that a full-wave rectifier utilizes both halves of the AC waveform, making it more efficient than a half-wave rectifier, which only uses one half. This is why the correct answer is 360 degrees, as it reflects the full utilization of the AC cycle.
