SUMMARY
The discussion clarifies the concept of electric power, specifically in the context of a transformer with an input power of 110 kW. It defines input power (P = UI) as the sum of the power used by the device and the power lost as heat in the cables. The conversation emphasizes that 110,000 joules of electrical energy are transmitted every second, highlighting the distinction between input and output power in transformers, which can differ due to energy losses.
