The instrument and methods of measurement described in this paper were developed to meet the frequent need of means for easily and accurately calibrating alternating-current instruments - ammeters and voltmeters, whatever their capacity; also to suggest an inexpensive method of measuring with high precision very large alternating currents regardless of their wave form or frequency. Incidentally the instrument and methods should prove sufficient for the accurate measurement of currents of very high frequency where ordinary methods would not be applicable.
