Hardcover. Condizione: Near Fine. No Jacket. 2nd Edition. Essentials Of Alternating Currents by Timbie & Higbie. Classic instruction representing the essentials a worker on alternating-current devises should know well. Developed through the experience of the authors in teaching short, intensive trade courses for electric wiremen. It is written in simple language and avoids use of algebra and trigonometry. The book covers modern systems of power transmission, transformers, impedance, power and power factor, current and voltage relations in series and parallel circuits, relation between impedance, resistance and reactance, polyphase circuits, calculation of wire sizes for various distributing systems, motors starters and controllers, converters and rectifiers. x + 377pp. The 2nd edition was copyrighted 1939. The revision was done by Professor Samuel H. Caldwell, of the Department of Electrical Engineering at M.I.T. The major need for revision came from the improved methods of starting and protecting alternating-current motors, expanded use of static condensers for power factor correction, the introduction of more efficient rectifying devices and the extensive development of the small capacitor motor applications during the 20 years after the 1st edition. Dr William Henry Timbie (1877-1959), was Professor of Electrical Engineering at MIT, co-leader of Industrial Cooperative program at MIT (1919-1947), author of several texts on electricity and electrical engineering, including Elements of Electricity and Principles of Electrical Engineering. Henry Harold Higbie?s (1882-1947) work in illumination established University of Michigan as a leader in the field. Hired in 1905, he was named President of the Illuminating Engineering Society in 1926-27, and he wrote the pioneering book, Lighting Calculations in 1934. No longer a focus of electrical engineering, Illuminating Engineering is concerned with both natural and man-made lighting in public and private buildings and homes. Hardcover has blue cloth boards with brown lettering & shadowboxes on spine and front, but no DJ. Interior is tight, clean and unmarked. Book is in remarkably fine condition, but has a impact mark on front cover from storage. Copyrights 1919, 1938, & 1946. Stated 2nd edition, 1939. This copy from 10th printing in May, 1958.

Paperback. Condizione: New. Print on Demand. In this essential handbook, the author presents a comprehensive and accessible guide to alternating current electricity, aiming to equip readers with a solid foundation in understanding the fundamentals and practical applications of AC circuits. Starting from basic principles, the book gradually introduces the concepts of frequency, cycles, voltage, and current, and how these factors interact in AC systems. It delves into the operation and construction of transformers, providing insights into how they enable efficient voltage conversion. The author then examines the concepts of impedance, power, and power factor, elucidating their significance in AC circuits. Throughout the book, the author emphasizes the practical aspects of AC electricity, with a focus on its applications in electrical wiring, lighting, distribution systems, and other common electrical devices. By presenting a balanced blend of theory and practical examples, this book offers a valuable resource for anyone seeking to gain a fundamental understanding of alternating current electricity. It is particularly useful for electricians, electrical engineering students, and anyone looking to expand their knowledge of electrical principles.
