}An absolute determination of the ampere has been made with the current weigher erected by AYRTON, MATHER, and SMITH in 1905, modified as described below. A detailed description of this instrument was given at the time of its erection. It will be sufficient to recall that it is a physical balance with two similar coil systems, one on each side of the central post, fig. 1, Plate 2. Each system consists of two cylindrical coils, of which only the outer one, which has two similar windings separated… Expand
