Homework Help: Complex power

  1. Feb 17, 2014 #1
    So I was reading through my course's lecture slides and it appears to contradict.

    In one slide it states that the average power, P = VrmsIrmsCos(phi)

    in another slide it states that the real power, P = VrmsIrmsCos(phi)

    Which one is correct?

    Since the rms value is the average value, and they are used to calculate real power.. the equation is calculating average real power
