Abstract

An alternating current bridge is described which may be used for measuring large capacities in series with high resistances or small phase angles in high resistance boxes. Using this bridge it is possible to compensate for the capacity and inductive effects in the standard resistance boxes and in the arms of the bridge. This correction is effected by the method developed for the adjustment of the Wagner earthing arm. Circuit equations are given to show the extent to which errors are eliminated, and experimental results in some typical cases are shown.
