Electric Power

[phyphysics]

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.

[Pengwuino]

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

[phyphysics]

how about input power and output power?

... sounds like theres an extra complication about this problem or else itd obviously be the same #'s
