Knowledge of fundamentals is critical to the success of a modern electrical technician, and this book explores direct current (DC) principles and methods as well as the underlying theories and concepts needed for a strong foundation in electrical technology. Readers are introduced to the fundamentals of electricity and DC circuits, including how properties of materials are categorized into conductors, semiconductors, and insulators. In-depth coverage of Ohm's law and its relation to voltage, current, resistance, and power is presented, followed by the theory and practical applications of electrical components connected in series. Later chapters examine DC parallel circuits, DC combination circuits, magnetism and generators, and DC circuit analysis tools that electricians will find invaluable in analyzing and understanding more complex circuits likely to be encountered on the job. Although based on DC circuits, the information supplied in this book will apply to alternating current (AC) circuits as well. This book contains much of the material that forms the foundation of electrical knowledge.
APPLIED CODEOLOGY: NAVIGATING THE NATIONAL ELECTRICAL CODE 2017 offers the perfect solution for any electrical professional who has ever felt overwhelmed when trying to locate specific information within the vast catalog of standards and articles contained in the NEC. As the world's predominantly adopted and enforced electrical installation standard, the code is a critical reference tool for anyone working in the field of electrical installation or maintenance. Recognizing that in order to use this resource proficiently a complete understanding of the outline format is necessary, the book introduces simple techniques that allow readers to quickly identify and locate various NEC sections. Readers then learn to qualify their electrical questions and efficiently and accurately access the necessary information within the code.
Advanced building automation technologies include a decision-making ability within the individual control devices, which are linked by a common data communication protocol that governs the electronic signals passed between devices to ensure that they are all speaking the same language. If the structure of the protocol language is available to all manufacturers so that they can produce and market compatible control devices, then it is known as an open protocol. Building Automation: System Integration with Open Protocols is the second book in a two-book series on building automation. The first book, Building Automation: Control Devices and Applications, addresses the basic functions of buildin...
