What is Electrical power: Definition and 55 Discussions

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electric power grid.
Electric power can be delivered over long distances by transmission lines and used for applications such as motion, light or heat with high efficiency.

    Inventing Wireless Electrical Power: My Dad and Nikola Tesla

    me and my dad were having a conversation about nikola tesla last night and he was saying how todays world needs to invent a wierless source of electrical energy. Kind of like radio, but instead of getting a weak electromagnetic signal, you would get a strong powerful signal that could maybe...
