Synopsis
Excerpt from Resistance Coils for Alternating Current Work
In an ideal resistance coil for alternating-current work two requirements need to be fulfilled, (1) the resistance must be independent of the frequency and (2) the phase angle must be zero. The design of coils which will fulfill these conditions as nearly as possible presents several interesting problems and the solution in any given case will depend upon the magnitude of the resistance of the coil. In order that some of the difficulties may be appreciated, a theoretical discussion of the factors which must be considered in the design of such a coil will be given. This will be followed by a description of the designs which have been found satisfactory, together with some suggestions as to proper methods of connecting the coils when they are to be used in a resistance box.

Resistance Coils for Alternating Current Work (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book offers a detailed exploration of alternating current resistance coils. The author begins with theoretical discussion of the conditions that must be met in constructing such coils for minimal phase angle and negligible resistance change with frequency. These principles are then applied to the design of coils of varying denominations. Specifications are provided for coils ranging from 1 to 10,000 ohms, accompanied by measurement results from sample coils constructed according to these specifications. Additionally, the author draws comparisons between the constants of these coils and those of commercial coils. Suggestions are also given for connecting coils in resistance boxes. The theoretical background, practical applications, and comparative analysis provided in this book make it a valuable resource for understanding and working with alternating current resistance coils. 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 # 9781333844356_0
