In most homes, **AC (Alternating Current)** is used, not DC (Direct Current). AC is preferred for household electricity because it is easier and more cost-effective to generate and transmit over long distances.
However, **DC** is used in some specific applications within homes, such as:
- **Batteries**: DC is used in battery-powered devices like flashlights, remote controls, and rechargeable devices (e.g., laptops and smartphones).
- **Solar Panels**: Solar panels generate DC, but the electricity is often converted to AC for household use through an inverter.
- **Electronics**: Many household electronics (like TVs, computers, and chargers) use DC internally, even though they are plugged into AC power. They usually have an internal power supply that converts AC to DC.
So, while homes use AC for most of their power needs, DC plays an important role in specific devices and technologies.
