I want someone explain when rms is complex. From the definition of it, it should be the effective dc value that gives the same effect and since dc values aren't complex how come in the text book (Alexandar fundamentals of electric circuits 9th edition) consider in problems some rms to complex and use this theory in proving complex power.
From the equation
Vrms = square root of ( (1/T) * integration(v(t)^2))
Integration boundaries: 0 to T
even if v(t) is under the x-axis due to charging a source v(t) ^ 2 will be above the curve and the integration should always be positive.
Therefore, no imaginary parts are to exist.
(even in case some miraculous happened that the integration is negative should Vrms be just imaginary not cmplex)
I hope someone help!
