Book excerpt: Excerpt from Absolute Measurements: In Electricity and Magnetism This little book was originally intended to be mainly a reprint of some papers on the Measurement of Electric Currents and Potentials in Absolute Measure contributed to Nature during the winter of 1882-3; but as these were being reprinted, many alterations and additions suggested themselves, which it was thought would render the book more generally useful. Most of the additional matter is mentioned in the introductory chapter, but I may here refer to a sketch of the theory of alternating machines, and of methods of measurement available in such cases, contained in Chapter X., and to Chapter XII. on the Dimensions of Units, which I have thought it desirable to introduce.

Download or read book An Introduction to Physical Measurements written by F. Kohlrausch and published by Forgotten Books. This book was released on 2018-02-27 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Introduction to Physical Measurements: With Appendices on Absolute Electrical Measurement, Etc The Author, in the preface to the second German edition, gives a sketch of the purposes which he hopes that the pre sent book will serve. He says, a truth which all experience confirms, that the mere verbal teaching of physical laws is seldom of much use, tending frequently merely to confuse the student; while the simple performance of an experiment gives him confidence in himself and in the laws he is investi gating, and leads him, by means of measurements which can be independently verified, to that knowledge of his powers which is so important when he has to do any original work. Since the greater part of the treatise is devoted to measure ments of physical quantities, we have thought its object better expressed by the title we have given it than by a literal translation of the German one. Descriptions of apparatus are but rarely given, as students mostly have instruments provided for them, and seldom have to make their own apparatus, or to put it together. The mathematical knowledge required is but very ele mentary, as the proofs of the formulae are only given when they present no complex arguments.

Book excerpt: Excerpt from The Theory and Practice of Absolute Measurements in Electricity and Magnetism, Vol. 2 of 2: Part II The sensibility of a galvanometer may be defined as the reciprocal of the current required to produce a definite small angular de ection of the needle, or, which comes to the same thing, it may be taken as measured by the angular de ection produced by a specified current, for example, a micro-ampere (one millionth of an ampere). Frequently if the galvanometer be a re ecting one it is regarded as inversely proportional to the current required to produce a de ection of one division of the scale, but this of course is a function of the arrangement of mirror and scale, and not merely of the coil.

This book was released on 2018-02-13 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Determination of the International Ampere in Absolute Measure Inasmuch as precise electrical measurements are usually made in terms Of standard resistances and standard cells, it would simplify the problem if a voltage instead Of a current were directly determined in absolute measure. The direct determination Of the volt with precision in absolute measure, however, presents very formidable difficulties and has never been made. It was largely for this reason that the ampere was chosen as the second independent unit instead Of the volt. Many absolute measure ments Of the ampere and Of the Ohm have, however, been made since Gauss and Weber first showed in 18 32 that a system Of absolute units is possible. These determinations, having been made at different times and at different places, can be com pared only by comparing the various concrete standards adopted at the different times. As there can be no concrete standard ampere, two expedients have been adopted for preserving the results Of the absolute measurement Of current. That most favored in the past is to determine the mass Of silver deposited per second in a silver voltameter by a current Of one ampere; the other, which in many cases in the past served as intermediary between the absolute determination and the silver voltameter measurement, is to determine the electromotive force of a certain standard cell in terms of a standard of resistance and the absolute ampere determined by the balance.

Download or read book Electrical Measurements Classic Reprint written by Frank A. Laws and published by Forgotten Books. This book was released on 2017-09-15 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrical Measurements In this book it is intended to give a general treatment of the subject of electrical measurements, special emphasis being placed on those matters which are important to the student of electrical engineering. In preparing a book of this character one has to consider, not only the mature reader who may desire a compendium of methods together with certain practical suggestions, but the student who is beginning the study of Electrical Engineering and who should acquire early in his course a sound knowledge of the process of electrical measurement. This knowledge is fundamental not only to much of the work which the student is required to do in the dynamo laboratory as a matter of engineering training, but to an adequate understanding of electrical testing as it is eu countered in the practice of the electrical engineering profession. In the preparation of the text this second class of readers has been particularly in mind. It is assumed that those who use this text have had courses in physics, the theory of electricity, and in mathematics, such as are given to third year students in technical schools of the first rank.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrical Measurements: A Laboratory Manual Progress in the methods of Electrical Measurement is quite as marked as in the applications of electricity. The perfecting of measuring instruments keeps pace with the demands imposed by scientific accuracy. Laboratory practice should not be permitted to lag behind discovery and commercial applications; obso lete methods may with propriety be relegated to historical collections, along With antiquated apparatus, so that students in electricity may learn only the latest modes of procedure. The authors of this book have proceeded on this plan in collecting and devising methods to form a graded series of experiments for the use of several classes in electrical measurements. How well they have succeeded others must decide. Quantitative experiments only have been introduced, and they have been selected with the object of illustrating the general methods of measurement rather than the applications to specific departments of technical work, such as submarine cable testing, telegraphy and telephony, or dynamo electric machinery. It is thought to be better that these subjects should be treated in Special handbooks. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Systems of Electrical Units written by Francis Briggs Silsbee and published by . This book was released on 1962 with total page 60 pages. Available in PDF, EPUB and Kindle. 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 Optical Trapping And Manipulation Of Neutral Particles Using Lasers A Reprint Volume With Commentaries written by Arthur Ashkin and published by World Scientific. This book was released on 2006-12-29 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important volume contains selected papers and extensive commentaries on laser trapping and manipulation of neutral particles using radiation pressure forces. Such techniques apply to a variety of small particles, such as atoms, molecules, macroscopic dielectric particles, living cells, and organelles within cells. These optical methods have had a revolutionary impact on the fields of atomic and molecular physics, biophysics, and many aspects of nanotechnology.In atomic physics, the trapping and cooling of atoms down to nanokelvins and even picokelvin temperatures are possible. These are the lowest temperatures in the universe. This made possible the first demonstration of Bose-Einstein condensation of atomic and molecular vapors. Some of the applications are high precision atomic clocks, gyroscopes, the measurement of gravity, cryptology, atomic computers, cavity quantum electrodynamics and coherent atom lasers.A major application in biophysics is the study of the mechanical properties of the many types of motor molecules, mechanoenzymes, and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Unique in vitro and in vivo assays study the driving forces, stepping motion, kinetics, and efficiency of these motors as they move along the cell's cytoskeleton. Positional and temporal resolutions have been achieved, making possible the study of RNA and DNA polymerases, as they undergo their various copying, backtracking, and error correcting functions on a single base pair basis.Many applications in nanotechnology involve particle and cell sorting, particle rotation, microfabrication of simple machines, microfluidics, and other micrometer devices. The number of applications continues to grow at a rapid rate.The author is the discoverer of optical trapping and optical tweezers. With his colleagues, he first demonstrated optical levitation, the trapping of atoms, and tweezer trapping and manipulation of living cells and biological particles.This is the only review volume covering the many fields of optical trapping and manipulation. The intention is to provide a selective guide to the literature and to teach how optical traps really work.
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.
