# How can we visualize active reactive and apparent power as areas in time domain?

Regarding AC power feeding an impedance, is it possible to plot an example of V and I versus time for an inductive load R+jwL and especially the instantaneous power on the same plot where we can mark/paint three different areas for a power period where one area will show the active power the other reactive and the other apparent power?

Instead of using phasors, I would like to see in time the areas corresponding to three types of powers namely active reactive and apparent.

• Reactive and apparent power don't exist in the time domain. They only exist as average quantities. Mar 16, 2019 at 19:10
• Yes thats why am asking the area per period. Energy per period. Mar 16, 2019 at 19:11
• Showing the the areas to be averged I mean Mar 16, 2019 at 19:15
• As for myself, there are may be a lot better answers on the internet, and might be redundant to answer it here. If you have a DSO, by multiplying the current and voltage at both channel you can see the plot, if the resulting parts of the power plot is positive then you have a load consuming power acting as active power, otherwise if it's negative the load is generating power acting as a reactive power.
