Electric Circuit Analysis

Alexander and Sadiku's fifth edition of Fundamentals of Electric Circuits continues in the spirit of its successful previous editions, with the objective of presenting circuit analysis in a manner that is clearer, more interesting, and easier to understand than other, more traditional texts. Students are introduced to the sound, six-step problem solving methodology in chapter one, and are consistently made to apply and practice these steps in practice problems and homework problems throughout the text.

This book is about electric energy: its generation, its transmission from the point of generation to where it is required, and its transformation into required forms. To achieve this end, a number of devices are essential-such as generators, trans­ mission lines, transformers, and electric motors. We discuss the design, construc­ tion, and operating characteristics of the electric devices used in the transformation to and from electric energy. This text is designed to be used in a one-semester course in electric energy con­ version at the second-year level of the Bachelor of Engineering course. It is assumed that the student is familiar with the laws of thermodynamics and has taken a course in basic circuit analysis, including the application of phasors. We begin with a discussion of how humankind has successfully harnessed the energy of wind, water, the sun, biomass, animals, geothermal sources, fossils, and nuclear fission to make its life comfortable. Some of the consequences of this activity on the environment are examined. In Chapter 2, we review the basic physics of energy and its conversion. This may be, to some extent, a repetition of knowledge gained in high-school and first­ year university courses. However, we believe that such review is necessary to establish a suitable base from which to launch the subject of electric energy con­ version.
