296 THERMO-ELECTRICITY, pile, with the addition of conical reflectors, is shownin Fig. 205. A change of temperature at either exposedface of the pile produces a feeble current of electricitywhich is manifested by the movement of the needle of the galvanometer. The instrumentis much used in… … Fig. 205. 433. The Peltier Ef-fect.—When an electric cur-rent passes over a junctionfrom antimony to bismuth,there is an evolution of heat atthe junction, the temperatureof which rises. When the current passes in the op-posite direction (from bismuth to antimony), there is anabsorption of heat and…
