(a) A thermopile consisting of 5 junction pairs of chromel-constantan is used to measure a temperature difference of 50oC with the cold junction at 25^oC. Determine the voltage output of the thermopile. What is its sensitivity?

Given E25 = 1.495 mV and E75 = 4.657

(b) Calculate thermistor temperature sensitivity for a thermistor at 100oC. Thermistor Resistance at 100oC is 100 ohms. Take Beta = 4120 k @ 100^oC. (hint: Use the thermistor resistance temperature relation, R =Ro exp {Beta((1/T)-(1/To))}.
