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.

This book was released on 2018-02-10 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Temperature Coefficient of Resistance of Copper For the resistance measurements the wires were placed in a specially designed oil bath with provisions for efficient stirring of the oil, for heating and cooling, and for temperature regulation. The wire was held between heavy clamps through which the cur rent was introduced. For conductivity determinations the resist ance was measured between knife edges mounted 1 meter apart on the marble base. The Thomson bridge method was used for measuring the resistances, employing a double set of variable ratio coils; an accuracy of 1 in 10 000 Was easily attained. The resist ance of the copper sample was compared with the resistance of a copper standard in the same bath as the test sample. The copper standards were Wires carrying soldered potential leads and placed in frames having connections for both current and potential leads. These connections dropped into mercury cups on the marble base in the oil bath. The resistances of the copper standards were compared from time to time with manganin resistance standards which were kept in a separate oil bath. The method of comparing the copper samples with a copper standard has the advantage that accurate temperature measurement is unnecessary.

Download or read book A New Method for the Absolute Measurement of Electric Quantity Classic Reprint written by Burton Mccollum and published by Forgotten Books. This book was released on 2018-02-08 with total page 32 pages. Available in PDF, EPUB and Kindle. 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 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.

This book was released on 2016-09-26 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Measurement of the Inductances of Resistance Coils Two standards of I - ohm resistance were prepared, both of manganin wire mm in diameter, the wire in one being arranged in a loop with the two legs I cm apart, while in the other it was bent into a circle of cm radius with a. Gap of cm between the ends. Each standard was provided with binding posts, in one case set perpendicular to the plane of the parallel wires, and in the other perpendicular to the plane of the circle. The self inductance of the binding posts was calculated and the mutual inductance with respect to the wire was assumed to be negligible. The inductances were calculated, giving the following values: Parallel wires. Circle. 279 437 8 End 22 Gap correction 4 Binding posts 4 Binding posts 291 cm 419 cm.
