A house typically runs on **alternating current (AC)**, not direct current (DC).
AC is used because it’s more efficient for transmitting electricity over long distances. It can easily be stepped up or stepped down in voltage using transformers, which makes it ideal for power distribution from power plants to homes.
In a home, the electrical outlets provide AC power, which is what runs most appliances like lights, refrigerators, and air conditioners. Some devices, like your phone, might use DC (since batteries store DC), but they convert the AC from the outlet into DC to charge the battery.
So, to summarize: **The electricity in your house is AC**.
