Paperback. Condizione: New. Print on Demand. This book dives deep into resistance standardization, a measure of an electrical circuit's opposition to current flow. It details a novel design for standard resistors that counters the effects of humidity, a problem that plagued earlier standards. The author, a scientist at the National Bureau of Standards, traces the historical use of resistance standards and the challenges faced by existing methods. The book explores the impact of humidity on shellac-coated coils, causing resistance fluctuations and measurement errors. Through experimentation with various oils and coil designs, the author discovered a solution: encasing the coils in airtight containers filled with pure oil. This innovation revolutionizes resistance standardization by providing stable and accurate measurements. The book not only presents the new design but also delves into the temperature coefficients of manganin wire, a crucial component in resistance standards. The author emphasizes the importance of small temperature coefficients for precise measurements and shares valuable data on the variations observed in different wire samples. Overall, this book offers a significant contribution to the field of electrical measurements. Its detailed analysis and practical solutions advance our understanding of resistance standardization and pave the way for more accurate and reliable electrical measurements in various applications. 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.…
