Book excerpt: Excerpt from A New Method for the Absolute Measurement of Electric Quantity In the absolute measurement of current two classes of methods are available which are capable of considerable accuracy, viz, electrodynamometer methods, in which the torque exerted between a fixed and a movable coil is measured and the current in the coils calculated from this measured torque and the known dimensions of the coil; and current balances, in which the force exerted between two coils carrying the current to be measured is balanced against a known weight and the current calculated from the weight and previously determined constants of the coils. By the latter form of apparatus measurements of current have been made in which a higher degree of accuracy has been attained than with the first-named type. There are, however, numerous possible sources of error in the use of the current balance, and, although most of these can be made small individually, they may on account of their number, introduce uncertainty in the result. The ordinary electrodynamometer methods as well as the current balance require in effect two separate experiments, the first for the determination of the value of the current in terms of a torque or force, and the second for the recording of this current in terms of the electro-chemical equivalent of silver or of a resistance and standard cell. This second experiment may introduce additional possibilities of error, owing to variations in the strength of the current or the voltage of the standard cell, errors in the resistances of the potentiometer circuits and thermo-electromotive forces in the galvanometer and potentiometer circuits, etc., and while these errors can be made small, still their possible presence increases the difficulties of the measurements. Although the current balance is capable of yielding a high degree of accuracy, it is not desirable to depend on the value given by a single type of apparatus, even though the experiments may be repeated with good agreement by different experimenters and with different instruments. It is highly desirable that if possible the values be checked by some other method, using a totally different type of apparatus.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Absolute Measurement of Inductance It occurred to us that a modification of the method quoted above from Gray would be as well adapted to precision measurements as any other proposed. Instead of using the electrometer to measure the difference of potential at the terminals of the inductive coil and of a fixed resistance R, we vary the resistance R until the difference of potential at its terminals is equal to that at the terminals of the308a.

This book was released on 2017-12-24 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Treatise on the Measurement of Electrical Resistance The determination Of resistance is the cardinal operation in electrical measurement, in the same sense that the comparison of masses is the cardinal operation in quantitative chemistry, or that of linear and angular distances in geodesy and surveying; and for similar reasons. The electrical resistance of many stable bodies is known to be a highly characteristic and permanent quality, and indeed is probably so of all its measurement in terms of other resistances is performed with great ease: the exactness of the result does not depend on very accurate construction of the apparatus used and this apparatus may be easily made of great sensibility. The measurement of resistance is little inferior, in point of exactness, to that of mass, and superior to that of angular or linear distance.

Download or read book Evaluating Measurement Accuracy written by Semyon G Rabinovich and published by Springer Science & Business Media. This book was released on 2013-07-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Evaluating Measurement Accuracy, 2nd Edition” is intended for those who are concerned with measurements in any field of science or technology. It reflects the latest developments in metrology and offers new results, but is designed to be accessible to readers at different levels: scientists who advance the field of metrology, engineers and experimental scientists who use measurements as tool in their professions, students and graduate students in natural sciences and engineering, and, in parts describing practical recommendations, technicians performing mass measurements in industry, quality control, and trade. This book presents material from the practical perspective and offers solutions and recommendations for problems that arise in conducting real-life measurements. This new edition adds a method for estimating accuracy of indirect measurements with independent arguments, whose development Dr. Rabinovich was able to complete very recently. This method, which is called the Method of Enumeration, produces estimates that are no longer approximate, similar to the way the method of reduction described in the first edition removed approximation in estimating uncertainty of indirect measurements with dependent arguments. The method of enumeration completes addressing the range of problems whose solutions signify the emergence of the new theory of accuracy of measurements. A new method is added for building a composition of histograms, and this method forms a theoretical basis for the method of enumeration.Additionally, as a companion to this book, a concise practical guide that assembles simple step-by-step procedures for typical tasks the practitioners are likely to encounter in measurement accuracy estimation is available at SpringerLink.

This book was released on 2011-10-24 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The epic story of the invention of a global network of weights, scales, and instruments for measurement. Millions of transactions each day depend on a reliable network of weights and measures. This network has been called a greater invention than the steam engine, comparable only to the development of the printing press. Robert P. Crease traces the evolution of this international system from the use of flutes to measure distance in the dynasties of ancient China and figurines to weigh gold in West Africa to the creation of the French metric and British imperial systems. The former prevailed, with the United States one of three holdout nations. Into this captivating history Crease weaves stories of colorful individuals, including Thomas Jefferson, an advocate of the metric system, and American philosopher Charles S. Peirce, the first to tie the meter to the wavelength of light. Tracing the dynamic struggle for ultimate precision, World in the Balance demonstrates that measurement is both stranger and more integral to our lives than we ever suspected.
Download or read book Methods of Measuring Electrical Resistance written by Edwin F. Northrup and published by Forgotten Books. This book was released on 2015-06-26 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Methods of Measuring Electrical Resistance This treatise contains a compilation of many methods of measuring electrical resistance, most of which are fully described. Some of the methods are new and are described here for the first time. Several are illustrated with records of sample measurements. While it is not claimed that the work is exhaustive, the author has selected for presentation all methods which in his judgment are useful, for commercial tests and measurements, for purposes of instruction in educational institutions and for application in technical and research laboratories. Rules for the estimation of errors are briefly considered in the first chapter. One chapter is devoted to methods of measuring temperature by means of resistance measuring apparatus, and in another chapter methods are considered for locating faults upon telephone and other land lines. While few descriptions of specific types of instruments are given, two chapters are devoted to a consideration of the broad principles which should apply when designing, selecting and using apparatus intended for the measurement of electrical resistance. An appendix contains data and information useful in connection with the subjects treated. Methods employed for the absolute determination of the ohm are not considered because few persons have occasion to make this determination. In the examples recorded to illustrate specific methods, it may at times appear to some that the precision obtained is unsatisfactory. The measurements recorded, however, are real and not hypothetical cases, and they were made under such working conditions as ordinarily obtain. They are thought, therefore, to be more instructive than specially selected cases where the measurements have been made with unusual skill and care resulting in exceptionally high precision.

Book excerpt: The various systems of measurement, with their respective sets of units, used in the literature on electricity and magnetism are described in detail. Their historical development is summarized. The manner in which each is derived from either of the two alternative points of view of the experimentalist and the theoretician is compared and contrasted. The desirability of recognizing both points of view in international standardization, particularly when discussing rationalization, is pointed out. The present status of the absolute measurements on which all electrical units are based is reported, and tables are included for the conversion of equations and numerical values from one system to another.
Download or read book The Adult Learner written by Malcolm S. Knowles and published by Routledge. This book was released on 2020-12-20 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do you tailor education to the learning needs of adults? Do they learn differently from children? How does their life experience inform their learning processes? These were the questions at the heart of Malcolm Knowles’ pioneering theory of andragogy which transformed education theory in the 1970s. The resulting principles of a self-directed, experiential, problem-centred approach to learning have been hugely influential and are still the basis of the learning practices we use today. Understanding these principles is the cornerstone of increasing motivation and enabling adult learners to achieve. The 9th edition of The Adult Learner has been revised to include: Updates to the book to reflect the very latest advancements in the field. The addition of two new chapters on diversity and inclusion in adult learning, and andragogy and the online adult learner. An updated supporting website. This website for the 9th edition of The Adult Learner will provide basic instructor aids including a PowerPoint presentation for each chapter. Revisions throughout to make it more readable and relevant to your practices. If you are a researcher, practitioner, or student in education, an adult learning practitioner, training manager, or involved in human resource development, this is the definitive book in adult learning you should not be without.
