Module 4 : THERMOELECTRICITY Lecture 21 : Seebeck Effect

  • Published 2012


Thomoson effect of heat exchange in a circuit of a single metal in which a temperature gradient exists. Seebeck Effect : In 1821 Thomas Seebeck, a German physicist discovered that when two dissimilar metal ( Seebeck used copper and bismuth) wires are joined at two ends to form a loop, a voltage is developed in the circuit if the two junctions are kept at different temperatures. The pair of metals forming the circuit is called a thermocouple . The effect is due to conversion of thermal energy to electrical energy. The existence of current in the closed circuit may be confirmed by
