    Hi guys, I'm working with AC circuits. I have the equations for avg power and reactive power. P and Q resp. Those equations have a compent sin/cos (theta v - theta I) . Additionally P Q and S (complex power) form a triangle whose angle PS is Theta. Is theta=theta v - theta I?

    I feel like this is really obvious but I need a sanity check.

    There is no theta v or theta i. If you find it in a textbook, show me. Q = S * Sin(theta) and P = S * Cos(theta) . It is a simple right triangle.
