1) A chromel-alumel thermocouple is exposed to a temperature of 1560?F. The potentiometer is used as the cold junction, and its temperature is estimated to be 83?F. Calculate the emf indicated by the potentiometer.

2) Four iron-constantan thermocouple junctions are connected in series. The temperatures of the four junctions are 200, 300, 100, and 32?F. Calculate the emf indicated by a potentiometer.
