Abstract :
The method introduced in 1923 by E. Biffi is discussed. Formulae are obtained for ratio and phase angle and for the galvanometer current. Biffi´s formula for the ratio of current transformation is made more precise by the introduction of a term which takes account of the effect of the condenser current upon the ratio. This correction is necessary in accurate work. The application of the method to comparative tests is dealt with.
