Class Information
Number: 324/451
Name: Electricity: measuring and testing > A material property using thermoelectric phenomenon
Description: Subject matter wherein an electromotive force is generated by a temperature difference between the junctions in a circuit composed of two homogeneous electrical conductors of dissimilar compositions; or in a nonhomogeneous conductor, an electromotive force is produced by a temperature gradient in a nonhomogeneous region and used to identify the different types of materials forming the junctions or to measure properties of these materials.
