摘要: The simplest thermoelectric system is a closed loop made with two different metals connected in the form of junctions at both ends. In 1822–1823 Seebeck discovered an electric current owing through when are kept temperatures, so-called effect. This then works as power generator. Since flows system, each metallic branch there exists voltage difference V between its Let us consider simpler case one conductor which relevant field E associated to created by gradient ∇T temperature T. above mentioned experiment suggests relation = S∇T, (1) where S coefficient or thermopower.
