EMF of a thermocouple is approximately a _____ function of the temperature difference between the junctions.
linear
The EMF (Electromotive Force) generated by a thermocouple is primarily a function of the temperature difference between its junctions. In such a case, the correct relationship is linear. This means that the EMF produced is directly proportional to the difference in temperature between the hot and cold junctions of the thermocouple. This linear relationship is fundamentally based on the Seebeck effect, which states that a voltage (EMF) is induced in a circuit when there is a temperature difference along the length of the conductor. Thus, for small temperature differences, the EMF is a linear function of the temperature difference.
