Lessons In Electric Circuits Vol 2 Alternate Current

Circuit theory is a core course in every Electrical Engineering curriculum, with a wide range of applications to a variety of problems related to electrical systems and subsystems, such as power transmission systems, communication systems, control systems and electronics systems in general.This e book is the third volume of my e book series on Electric Circuits.In Volume 1, Introduction to Electric Circuits Theory, we present all fundamental concepts, definitions, principles and techniques on Electric Circuits, while In Volume 2, Direct Currents Circuit Analysis, we present a systematic analysis of DC circuits, i.e. circuits driven by DC sources.In the current volume we study Alternating Currents, i.e. the analysis of Electric Circuits driven by sinusoidal voltage and/or current sources. The content of this book is divided in 17 chapters.In Chapter 1 we introduce the periodic signals (wave forms), and define their average and RMS (effective) values, give a systematic and comprehensive introduction of the Algebra of Complex Numbers, (which greatly simplifies the analysis of AC circuits), introduce the extremely important Phasor Concept and show how to express sinusoidal functions of time by their Phasors representations.In Chapter 2 we develop the two fundamental Kirchhoff
