Energy storage and in particular electrical storage of energy has become a very talked about topics in circles, ranging from lay person in regard to hybrid and battery electric vehicles, to professional and certainly by legislators and energy policy makers in government. But even to professional the distinction between physical and chemical forms of electric energy storage are unclear and at times poorly understood, if at all. This book takes a critical look at physical storage of electricity in the devices known collectively as electrochemical capacitors and particularly as ultracapacitors. In its 12 chapters, this text covers ultracapacitors and advances battery topics with emphasis on clear understanding of fundamental principles, models and applications. The reader will appreciates the case studies ranging from commercial to industrial to automotive applications of not only ultracapacitors but these power device components in combination with energy dense battery technologies.

There are many 'Electric Circuits' books on the market but this unique Understandable Electric Circuits book provides an understandable and effective introduction to the fundamentals of DC/AC circuits. It covers current, voltage, power, resistors, capacitors, inductors, impedance, admittance, dependent/independent sources, the basic circuit laws/rules (Ohm's law, KVL/KCL, voltage/current divider rules), series/parallel and wye/ delta circuits, methods of DC/AC analysis (branch current and mesh/node analysis), the network theorems (superposition, Thevenin's/Norton's theorems, maximum power transfer, Millman's and substitution theorems), transient analysis, RLC circuits and resonance, mutual inductance, transformers, and more.

In this digital age, as the role of electronic circuits becomes ever broader and more complex, a thorough understanding of the key concepts of circuits is a great advantage. This book offers a thorough reference guide to the theory, elements and design of basic electric circuits, providing a solid foundation for those who plan to move into the field of electronics engineering, and essential information for anyone who uses electric circuitry in their profession or research. The book is designed to be accessible to newcomers to the field while also providing a useful review for more advanced readers. It has been extensively revised and expanded for this new edition to provide a clear source of information on this complex topic. Materials are presented visually with less text and more outlines so that readers can quickly get to the heart of each topic, making studying and reviewing more effective.
