Is home electricity AC or DC?

in Electrical Engineering

Is home electricity AC or DC?

1 Answer

Home electricity is **AC** (Alternating Current).

AC is used in homes because it’s more efficient for transmitting electricity over long distances. The voltage in AC changes direction periodically, which makes it easier to step up or step down the voltage using transformers, reducing energy loss during transmission.

In most homes, the standard AC supply is 110V or 220V depending on the country.

DC (Direct Current), on the other hand, flows in one direction and is commonly used in devices like batteries, electronic gadgets, and some smaller appliances.
