The three-phase alternating current system is universally used in production, transmission and utilization of electrical energy. Knowledge of the concepts and principles underlying its operation, as well as the methods of measuring characteristic quantities, is essential baggage for the technician skilled in electrical and electronic technologies.The present volume, divided into three chapters: the three-phase system, three-phase power, and the measurement of three-phase power, enab...

A book you read, and a laboratory you can play with.Most figures in this ebook are live: they are interactive cards, small simulations built by the author and embedded in the pages, that let you change a frequency, reverse a phase, vary the slip of a motor or add a harmonic, and watch the physics respond, without leaving the book.Please note – which reading apps run the cards• The cards run inside the book in reading apps that suppo...

Why does a complex number describe an alternating current? And how does that same idea lead all the way to the Fourier transform?This book answers both questions in ten carefully connected stages. It starts from one of the cornerstones of modern technology, AC circuit theory, and uses it as a gateway to some of the most powerful tools in mathematics.The first six chapters build a solid foundation in AC circuit analysis: sinusoids and phasors, the "magic" of...

"Electric Circuits" is the second volume in the series Fundamentals of Electrical and Electronic Technology. In the same spirit as the previous volume, the fundamental elements of the electrical circuit are considered, starting with series and parallel connections, through to the generalized Ohm's law of two-terminal components and a description of the behavior of voltage and current sources, including an analysis of energy aspects.This is a basic course, suitable for students as we...

This third volume in the series Fundamentals of Electrical and Electronic Technologies deals with the main and most popular methods of solving electrical networks. We discuss superposition of effects, star- delta transformations, Kichhoff's principles of course, node potentials analysis, Millman's theorem.Special consideration deserves Thévenin's theorem (with its dual Norton's theorem), a very powerful tool for simplification of complex networks, but often difficult in understandin...

"Ohm's Law" is the first in a series of lean volumes, with which the author, thanks to a long and consolidated teaching experience, aims to simply and quickly introduce readers to the world of electrical and electronic technologies.This is a basic course, suitable for students but also for workers who have undertaken a professional retraining process.Topics are developed in detail and rigorously, with clear and straightforward exposition."Let's Try Together" sections p...
