"Full DC in AC" typically refers to the process of converting alternating current (AC) into direct current (DC) using a method called **rectification**. In an AC supply, the direction of current flow changes periodically, while in DC, the current flows in only one direction.
### Rectification:
To convert AC to DC, you can use a rectifier. A **full-wave rectifier** is commonly used for this process. It allows both halves (positive and negative) of the AC waveform to be converted into DC.
### Full-Wave Rectification:
- In **full-wave rectification**, both the positive and negative halves of the AC waveform are used, which makes the output DC smoother and more continuous compared to half-wave rectification, which only uses one half of the waveform.
- The full-wave rectifier typically uses **diodes** arranged in a bridge or other configuration.
### Key Points:
- **AC**: Alternating current, changes direction periodically.
- **DC**: Direct current, flows in only one direction.
- **Rectification**: The process of converting AC to DC.
When you say "full DC in AC," it may refer to achieving a DC output from an AC input after using a rectifier, with the goal of smoothing out the current for use in devices that require DC power. However, pure "DC" is not naturally found in an AC source; it requires conversion through rectification.
