Working Principle of Thermocouple| What is Cold Junction Temperature

In this video, we will delve into the fascinating world of thermocouples and explore their working principle in depth. A thermocouple is a sensor used to measure temperature by utilizing the phenomenon of thermoelectric effect.
The basic idea behind thermocouples is the generation of a voltage when two different metals are joined together at two different temperatures. This voltage is directly proportional to the temperature difference between the hot and cold junctions of the thermocouple.
