E.m.f. generated by thermocouples is of the order of ________________?
Correct answer: A. Milli volts
- A. Milli volts
- B. Micro volts
- C. Volts
- D. Kilo volts
Explanation
Thermocouples generate a small thermoelectric voltage, normally measured in millivolts. Microvolts are too small for the usual industrial thermocouple output, while volts and kilovolts are far too large.
