0% .. ±i% * JX,\This method is independent of the battery voltage, in facta source of alternating e. m. f. may be substituted for thebattery and switch if the galvanometer is replaced by a tele-phone, an electrometer or an electro dynamometer. Thomsons method is somewhat better. As shown inFig. 40… … Hlllllllh-<>*>Fig. 39. its capacity can still be measured by using the optical tele-phone in place of the galvanometer and key and applyinga sinusoidal e. m. f. instead of a battery e. m. f. Aresistance Rs must also be placed in series with the othercondenser C2. Then if B0 is the ohmic…
