The power in most houses is **AC (Alternating Current)**.
AC is used because it is more efficient for transporting electricity over long distances. Power stations generate AC, and it's easier to step up or step down its voltage using transformers, which helps reduce energy loss during transmission.
However, some devices in your home, like laptops or TVs, use **DC (Direct Current)** power. These devices have internal power supplies that convert the AC from the wall into DC for their operation.
