Thermoelectric effects and contact potentials (for teachers)
The origin of thermoelectric effects occurring in metals is simply explained for the benefit of teachers. The Seebeck, Peltier and Thomson effects are described, in particular their use in measuring thermoelectric power. The theory of thermoelectric power is provided and in relation to the use of real metals. Thermocouple calibration is treated. Contact potentials and their effect on thermoelectric power are dealt with.
