2010-Properties of the Thermocouple

From McGill University Physics Department Technical Services Wiki

This experiment investigates a K-type thermocouple in order to demonstrate the Seebeck and Peltier coefficients. Temperature dependency of voltage and vice-versa are characterized for this thermocouple. A homemade thermocouple is built to find current which is found as 40.1 ± 0.5 mA with junctions in liquid nitrogen and at room temperature, and 196.8 ± 0.6 mA for junctions in liquid nitrogen and being heated by a blow torch.
