Electric Power

  1. Aug 5, 2005 #1
    What really does the word 'power" mean in the following context?

    An electric power of 110kW is transmitted through the cables.

    Input power of the transformer

    P = UI, this is the power the current heats the cable + the power the device in the other end is using.

    That means that 110,000 joules of electrical energy is being transmitted every second.
