If one had a series of v(t)i(t) product values, as many as needed, but no additional information, how would one go about separating the real and reactive powers from the instantaneous apparent power?
Are we to assume sinusoidal AC? ...and linear load?If one had a series of v(t)i(t) product values, as many as needed, but no additional information, how would one go about separating the real and reactive powers from the instantaneous apparent power?
apparent power is magnitude of complex power and how it could be instantaneous.

How many samples is "a series"? Enough to draw a fairly accurate complete single cycle?
He did say, "...as many as needed..."How many samples is "a series"? Enough to draw a fairly accurate complete single cycle?
"Apparent instaneous power" is acceptable terminology and is self explanatory.
Got Excel? Why not generate some numbers for us... but please not a googol. What would make it interesting is the product values not indicating the exact peaks or zero crossings.As many as you need, say a googol.
Nothing in my bookOk thanks for this than what is difference between the instantaneous complex power and instananeous apparent power.
"procut" is a typo for "product"....
Additionally, given only the procut values, there will likely be at least two answers. For example, |v||i| = |v'||i'|, where |v'| = |i| and |i'| = |v|.

It's still "complex" in the literal sense, being made up of two parts. It could be complex numerically if one chooses to describe the waveform as a sine function of time... nothing different than what we do with voltage and current.Instantaneous power cannot be complex because the addition is algebraic not phasorial. There is no power triangle as in the steady state.
Okay, show me the pic of a complete cycle.As many as you need, say a googol.
Perhaps this one...? (Nice and big so you can copy and draw on )Okay, show me the pic of a complete cycle.

Anyway, futher thought on the matter leads me back to saying there are two answers because we cannot discern leading or lagging current by vi product information alone.
I only see one waveform. Didn't your original question express two values?Perhaps this one...? (Nice and big so you can copy and draw on )
