That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.

It depends on poo
the power it is givin.
no
they both depend on weather
nope!
That would depend on the power supply.
Electrical power is not measured in doses. However medicine is.
Army/Troops
Horse power and gear ratio.
they depend on the tide and arent very realible
As power = work done/time, power depends upon magnitude of w.d. and time required.
If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
