Seebeck Coefficeints: Definition, Significance & Thermocouple Image

[chound]

what are Seebeck coefficeints? What do they signify?
Does anyone have a pic of a thermocouple?
What is thermopower?

 

[Astronuc]

The thermopower, thermoelectric power, or Seebeck coefficient of a material describes how it functions thermoelectrically.

The Seebeck coefficients, represented as S, are non-linear, and depend on the conductors' absolute temperature, material, and molecular structure.
