Vedclass · Answer

(A) The phenomenon described is the $Peltier$ effect,where heat is absorbed or evolved at the junction of two dissimilar metals when an electric current passes through it. In an antimony-bismuth thermocouple,when the current flows from antimony to bismuth,the junction absorbs heat (becomes cold),and when it flows from bismuth to antimony,the junction evolves heat (becomes hot). Therefore,the junction becomes hot when the current flows from bismuth to antimony.

When current is passed in an antimony-bismuth couple,then:
