1. The problem statement, all variables and given/known data
Hi guys,, need help with the following question :

3. The attempt at a solution
OK, first things first ,, what does the question mean by saying

?? and I know that real power equal I^2 R for series & V^2/R for parallel but the problem it doesn't say if it's series or parallel ,, so my second question is how to start solving the problem ?? (Don't give me answers please just tips )

It means that all the inductor is doing is causing a phase shift in the AC source. So the waveform will give an average voltage, current, and even power of zero.

If you decompose the complex impedance of the inductor you have a real part and an imaginary part. The real power is, just as it sounds, the real part of the power.

"The instantaneous power consumed by the load has zero average value" doesn't mean anything.

It's a misstatement or something; wrong in one and a half places:

The average power into the idealized inductive load is zero. The inductive load 'consumes' no power. The instantaneous power can be into or out of the load. Instantaneous power is just the power, positive or negative at any given instant, rather than over the entire AC cycle.
