2.6volts. With this arrangement the current in the thermometers was Dickinson.Mueller, ] Calorimetric Resistance Thermometers. 647 kept nearly constant at 0.0025 ampere. Experiments showed thatthis current raised the temperature of the thermometer coils o?oi05when in ice and o?oiio when in steam.… … 0.001 Fig. 3.—Diagrammatic sketch of bridge. The galvanometer used was of the Broca type, with vertical mag-nets, having their consequent poles at the center of the coils, andwas adjusted to a sensibility of about 600 megohms. With thescale placed at 50-cm distance, this gave a deflection of i mm…
