checking power consumption of circuit - ideal voltage source

[JoannesPaulus]

Power consumption

if you want to check the power consumption of your circuit from an ideal voltage source (no inductors, or resistors in series with the source), do you use the average or the rms functions? i.e.: average(IT('/V0')) or rms(IT('/V0'))?
Shouldn't they give the same results?

Power consumption

average.
The rms value and average value are different.
Positive value means the current flow from the power supply and the negative value means the current flow into the power supply.
For the negative value ,the power supply acts as a load.the load acts as a source.
So the power consumpted by the load should be substracted.
