Unformatted text preview: m the resistance and mul7ply voltage and current to get output power. Thermoelectric generator Experiment What difference in efficiency do you get for different load resistances? •  To measure the Pel7er coefficient apply one dc power supply to the thermoelectric and another to the heater. Use the heater to balance the cooling effect of the thermoelectric to produce zero temperature difference. Determine the input and output powers. A useful value to determine is the “Internal resistance” of the device. In other words, how much power is dissipated going from one power supply to another. Thermoelectric generator Experiment How does the Pel7er coefficient vary with power input? q = Heater Power = Pjthermoelectric...
