Question 1
A thermoelectric module has a Seebeck coefficient of 150 µV/K and operates at 350 K. If the temperature difference between the hot and cold sides is 50 K, what voltage is generated by the module?
💡 Hint: Use the Seebeck coefficient formula correctly to find the generated voltage.
Question 2
A new thermoelectric material has the following properties: Seebeck coefficient = 180 µV/K, electrical conductivity = 12 S/m, thermal conductivity = 0.5 W/m·K, calculate its ZT.
💡 Hint: Apply the ZT formula but pay special attention to unit conversions.
