In thermocouples which of the following pairs is commonly used ?
Correct answer: A. Copper-constantan
- A. Copper-constantan
- B. Aluminium-tin
- C. Silver-German silver
- D. Iron-steel
Explanation
Copper-constantan, also called a type T thermocouple, is a commonly used thermocouple pair for moderate temperature measurement. A thermocouple generates a voltage from the temperature difference between its junctions.
