15 Facts About Electrical power

Electric power is the rate at which electrical energy is transferred by an electric circuit.

Common misconception is that electric power is bought and sold, but actually electrical energy is bought and sold.

Electric Electrical power is usually produced by electric generators, but can be supplied by sources such as electric batteries.

Electric Electrical power can be delivered over long distances by transmission lines and used for applications such as motion, light or heat with high efficiency.

Electric power is transformed to other forms of energy when electric charges move through an electric potential difference, which occurs in electrical components in electric circuits.
