Page 302 - ... resistances, self and mutual inductances, and capacities. I propose to treat of the measurement of alternating currents, electromotive force, and watts in a separate paper. Resistances are ordinarily best dealt with by continuous currents, except liquid resistances. I propose to treat in this paper, however, mainly of inductances, self and mutual, and of capacities together with their ratios and values in absolute measure as obtained by alternating currents. I also give a few methods of resistance...
