SUMMARY

The discussion clarifies the distinction between average power and real power in electrical systems. Both average power and real power are calculated using the formula P = VrmsIrmsCos(phi), where Vrms is the root mean square voltage, Irms is the root mean square current, and Cos(phi) represents the power factor. The confusion arises from the terminology; average power refers to the mean value over time, while real power is the actual power consumed in a circuit. Thus, the equation provided is indeed applicable to both concepts, emphasizing their equivalence in this context.

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
