THERMOCOUPLE When two wires composed of dissimilar metals are joined at both ends and
one of the ends is heated, there is a continuous current which flows in the thermoelectric circuit. Thomas Seebeck made this discovery in 1821.
If this circuit is broken at the center, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals.
All dissimilar metals exhibit this effect.
