The Principles Involved in the Selection and Definition of the Fundamental Electrical Units to Be Proposed for International Adoption (Classic Reprint) - Softcover
Synopsis
How we define the basic electrical units and why it matters
This booklet explains the search for two foundation units and how they’re chosen to be accurate, concrete, and reproducible in laboratories around the world. It looks at the ohm and the second unit, and why the volt’s role is tied to those choices.
Two fundamental questions frame the discussion: which two units should be chosen, and how should their definitions be written so measurements stay consistent over time? The text compares the practical approaches of using a mercury-based resistance and a silver-based method, weighing their reliability, repeatability, and ease of use.
- Why accuracy of reproduction matters when defining base units
- How concrete standards enable direct comparison between labs
- The trade-offs between the coulometer method and standard cells
- How national laboratories can collaborate to test and harmonize specifications
Ideal for readers of standards work, metrology history, and the development of international measurement systems.

Paperback. Condition: New. Print on Demand. This book studies the complexities and history of the electrical units the ampere, volt and ohm. These play an important role in science and technology, and are significant enough to have been discussed at the International Electrical Congress. The book emphasizes how the three units have been fundamentally defined in terms of concrete and absolute standards, with insight into the distinctions between these standards. The text traces the practical and theoretical challenges that have come up in the process, including difficulties in reconciling absolute and international units, and methods of increasing accuracy via absolute measurements. Ultimately, the book analyzes which of these units provide the most benefit in terms of accuracy, concreteness and ease of reproduction. 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 # 9781333734039_0
