In order to calculate P, the real power absorbed by an impedance, we are to use \(P=|I_{rms}|^2*Z\), and why the modulus of \(I_{rms}\) (the magnitude) used instead of \(I_{rms}\) directly, if used what would it yield.
This is a sincere question as i am not able to comprehend why, and i think the text book i use, is giving only a vague insight into the power calculations from a problem solving point of view.
