THEORY
PELTIER EFFECT be called after a frenchwatchmaker (1785-1845.), who discovered it in 1834.
How does Peltiereffect work? If you put a drop of water in the hollow on the joint of 2 conductors or semiconductors, e.g. Sband Bi, and switch on the current, the drop would freeze If the reverse direction of the current is applied, the drop would melt.
