Thermocouple thermometer

Vedclass · Answer

(A) thermocouple thermometer consists of two dissimilar metal wires joined at two junctions. It works on the Seebeck effect, where a temperature difference between the junctions produces an electromotive force $(EMF)$. Because thermocouples have a very low thermal mass and high thermal conductivity, they respond very quickly to changes in temperature. Therefore, they are the ideal choice for measuring rapidly changing temperatures compared to gas, resistance, or vapour pressure thermometers, which have higher thermal inertia.

Of the following thermometers, the one which can be used for measuring a rapidly changing temperature is a
