Both the heat

The electrical series of the legs, that have opposite Seebeck coefficients (Sp > 0, Sn < 0), results in a potential drop proportional to the temperature difference: An eventual load, applied to this generator (schematically

Conversely, if an electrical current is forced through the legs by means of an external generator (Figure 2b), heat is transferred from the cold side to the hot
