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: Excerpt from A New Method for the Absolute Measurement of Electric Quantity 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. In electrodynamometers of the ordinary types the dimensions of the windings must be known with extreme accuracy, thus requiring that the coils not only be wound with great regularity and measured with great care, but permanency of both size and form must be assured. In the Gray electrodynamometer a greater difficulty still is met with in measuring the torque. This is accomplished by balancing the torque due to the current against the torsion of a wire, the constant of which has been determined by a separate experiment. The great difficulty in this lies in the erratic behavior of all materials available for the torsion wire. They can not be depended upon to remain constant with time, they vary considerably even with slight changes in temperature, and they all have a greater or less tendency to take a permanent set when twisted, as they must be, in use. Again, both electro dynamometers and current balances have a rather troublesome temperature coefficient, and, although artificial cooling may alleviate this condition somewhat, a certain amount of local heating is inevitable, and the consequent change in the dimensions may give rise to considerable variation in the constants of the instruments between the time of measuring the dimensions of the coils and the time of making a measurement of current. In what follows, there is described a type of electrodynamometer which, when used to measure the electrochemical equivalent of silver, appears to be free from the objections referred to above, and at the same time it is believed that no other difficulties of a serious nature are introduced.

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. During some years the author has superintended the construction of a large number of resistance coils, and of various forms of instruments for their comparison and measurement, and he thinks that a systematic account of the methods and processes employed may be useful to the large and increasing body of electricians who use such apparatus.
