Text Solution
Verified by ExpertsThe correct answer is:
B
A thermocouple measures the temperature difference between two junctions.
Step 1: Understand that a thermocouple consists of two different metals joined at one end.
Step 2: When the junction is heated, it generates a voltage that is proportional to the temperature difference between the hot junction and the cold junction.
Step 3: The device is commonly used to measure temperature differences rather than absolute temperatures or other properties.
Therefore, the correct answer is B.
