Seller rating 4 out of 5 stars
Paperback. Condition: New. Print on Demand. This book overviews the updates to the representation of volts and ohms in the US, effective January 1, 1990. The author provides detailed instructions on how to bring voltage and resistance standards and instrumentation into conformity with the new representations. They also include updated information on the International Temperature Scale of 1990 and the US representation of the farad. These updates are the culmination of technological advancements in measurement science and will eliminate problems with nonuniformity of national ohm representations, their variation in time, and their inconsistency with the SI. The author, a distinguished authority in the field, provides readers with a comprehensive understanding of the changes and their significance for accurate and consistent electrical measurements worldwide. 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. Seller Inventory # 9781390362695_0
