Is mains electricity AC or DC?

in Electrical Engineering

Is mains electricity AC or DC?

1 Answer

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

In most parts of the world, the electricity supplied to homes and businesses is AC. The current alternates direction periodically, meaning it flows back and forth. This is different from DC (Direct Current), where the current flows in only one direction.

AC is used for mains electricity because it's easier and more efficient to transmit over long distances compared to DC. The voltage can also be easily stepped up or down using transformers, which makes it ideal for the power grid.
