When a current is passed through a solid alloy, a series of Peltier effects, proportional to the current, are set up between the particles of the different metals, and these create an opposing electromotive force which is indistinguishable experimentally from a resistance.
When the Revolution developed the importance of the press, Rivarol at once took up arms on the Royalist side, and wrote in the Journal politique of Antoine Sabatier de Castres (1742-1817) and the Actes des Apdtres of Jean Gabriel Peltier (1770-1825).
Peltier (1785-1845) in 1814 discovered that a current passed across the junction of two metals either generated or absorbed heat.
JEAN CHARLES ATHANASE PELTIER (1785-1845), French physicist, was born at Ham (Somme) on the 22nd of February 1785.
