 AC Power Flow in Linear Networks by James L. Kirtley Jr.

MIT 6.061, Chapter 2, “Energy and Power”, equations45–63 and §7.1 RMS Amplitude, printed pp.10–15. Equation63 uses peak phasors and a factor 1/2; the RMS convention removes that factor. The first-page byline is J. L. Kirtley Jr.; its copyright names James L. Kirtley Jr.

The first page carries a 2007 copyright and the full name James L. Kirtley Jr.; the document is distributed in the Spring 2011 OCW course. Equation63 uses peak-amplitude phasors and includes a factor1/2; Section7.1 defines RMS amplitudes, under which complex power is $V{I}^{\ast }$.
