All the thermocouples used for temperature measurement use dissimilar metal ________________?
Correct answer: B. Wires
- A. Strips
- B. Wires
- C. Bars
- D. Beads
Explanation
A thermocouple requires two dissimilar metals joined to form a measuring junction, and these metals are normally provided as wires. The thermoelectric voltage results from the Seebeck effect.
