1. For a certain thermistor β = 3420 K, and the resistance at 200?F is known to be 1010 ± 3 Ω. The thermistor is used for a temperature measurement, and the resistance is measured as 2315 ± 4 Ω. Calculate the temperature and the uncertainty.
2. Calculate the thermoelectric sensitivity for iron-constantan and copper constantan at 0?C. Plot the error which would result if these values were assumed constant over the temperature range from -50 to +600?F.
