Paperback. Condizione: New. Print on Demand. This book offers a comprehensive study of the electrical conductivity of commercially available copper. It delves into the historical evolution of copper conductivity standards, providing a critical analysis of various values used by different institutions and countries. The author presents detailed experimental results obtained from measurements on samples furnished by leading copper refiners and wire manufacturers. These results shed light on the relationship between conductivity and factors such as annealing, drawing, and sample size. The book also explores the highest achievable conductivity in copper and presents data on the electrical properties of aluminum. The author emphasizes the practical significance of the findings, discussing their implications for wire tables, temperature coefficient assumptions, and the need for an international standard of copper conductivity. The insights provided in this book are valuable for researchers, engineers, and professionals involved in the electrical industry, as well as those interested in the history and standardization of electrical materials. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
