This document outlines the methodologies of Norton, Millman, and Kennely for solving complex electrical circuits. The Norton theorem reduces a circuit to a real current generator with a parallel resistance. The Millman theorem simplifies potential differences across parallel branches, and Kennely's transformation converts networks between star and triangle configurations. Practical applications and exercises illustrate the methods, including current calculations, equivalent resistance transformations, and network reductions.
