About this book
The absolute measurement of inductance
Year: 1905
The most obvious method of directly determining the inductance of a coil is that originally proposed by Joubert, and consists in first determining the impedance of the coil and then finding the ohmic resistance of the wire and the frequency of the current employed. In a variation of this method, described by Gray, a non-inductive resistance is placed in series with the coil whose inductance is to be measured, and an alternating current passed through both. By means of an electrometer the differences of potential at the terminals of the non-inductive resistance (R/sub 2/) and of the inductive coil (resistance R/sub 1/ and inductance L) are measured. The inductance is then given by the expre
