Talk:Power rating

Unnamed section
There is another kind of power rating, one that measure strength of sport teams in statistics.

Power Rating Main Definition
The main definition for the Power Rating indicated here equals it with the 'dissipated' power outputing a device. This is only correct for 'dissipative' devices, which immediately restrict the 'general' definition at the same moment.

The Power Rating of a device -being it dissipative or not- is the 'Maximum Input Power Allowed to flowing into a device'. The main definition here only helds for dissipative devices, which is not general. After that, this 'narrow' definition is 'widen' by including the 'efficiency' parameter, then mixing both dissipative and non-dissipative devices, hence confusing both kind of devices.

The definition also works when there is a primary efficiency, for fixing the definition. If there is not 'dissipation' nor 'mechanical' outputs -such as conversion to other energies part of the base purpose of the device-

Hence a 10kW laser could have a 1kW dissipating power and a 9kW LED output power a 10kW heating reactor could have 9kW heat power and 1kW for auxiliar systems, and a 10kW motor could have a 1kW dissipation and a 9kW transferred mechanical power. Clearly the dissipation, which is relevant, is not the key aspect here.

This should be corrected as soon as possible, whatever the time this definition has been lasted here. — Preceding unsigned comment added by Hypfco (talk • contribs) 06:10, 6 May 2015 (UTC)
