1 Answer

Answer :

Seebeck’s effect
Peltier effect
When two dissimilar metals are joined together so that two junctions are formed and if one junction is heated and other is cooled then electric current flows through it.
When electric current flows through a junction of two metals of thermocouple, then heat is generated at one junction and heat is absorbed at the other junction.
emf is developed across the two junction.
One junction gets heated and other get cooled.
emf generated is small in mV.
Heat generated or absorbed is small. 
Amount of heat generated depends on pair of metals and temperature difference.
Amount of heat generated depends on pair of metals and current through it.
