Page "Thomas Johann Seebeck" Paragraph 4

The voltage produced is proportional to the temperature difference between the two junctions.

The proportionality constant ( a ) is known as the Seebeck coefficient, and often referred to as the thermoelectric power or thermopower.

The Seebeck voltage does not depend on the distribution of temperature along the metals between the junctions.

This effect is the physical basis for a thermocouple, which is used often for temperature measurement.
