An AA battery provides DC (Direct Current).
Understanding DC Power
Batteries, including AA batteries, are a source of DC power. This means that the electrical current flows in one direction, from the negative terminal to the positive terminal. The direct current is generated through a chemical reaction inside the battery itself.
Key Differences Between AC and DC
| Feature | AC (Alternating Current) | DC (Direct Current) |
|---|---|---|
| Direction of Current | Alternating | One Direction |
| Source | Power Plants, Generators | Batteries, Solar Cells |
| Voltage | Changes over time | Constant |
| Typical Uses | Powering homes, large appliances | Powering electronics, portable devices |
Why AA Batteries Use DC
- Portable Electronics: Most portable electronic devices like remote controls, toys, and flashlights require DC power.
- Energy Storage: DC is the form in which electricity is stored in batteries.
- Simplicity: DC circuits are simpler and more efficient for low-power applications.
