1. Seebeck voltage (?) to temperature (T) conversion for thermocouples is often written in a power series of the form T = a0 + a1? + a2?2 + a3?3 + ... + an?n . Using this representation, determine the formula for the (a) Seebeck, (b) Peltier, and (c) Kelvin coefficients.
2. Determine the EPRD in a semiconductor thermoelectric junction that has the following physical properties:
Electrical resistivity = 1.10 × 10-5 ohm meters
thermal conductivity = 1.30 W(m · K)
Seebeck coefficient = (200. + 10.0 T - 0.0100 T2) × 10-6 V/K
Junction temperature = 400. K
The temperature gradient at the junction is 1000. K/m and the voltage gradient is 0.0300 V/m.
