1.	When two wires of different material are joined together at either end, forming two junctions which are maintained at a different temperature, a thermo-motive force is generated causing a current to flow around the circuit. This arrangement is called ___________(a) thermal pair(b) thermistor(c) thermocouple(d) thermostatI have been asked this question during an interview for a job.My question is based upon Transducers for Body Temperature Measurement topic in chapter Physiological Transducers of Biomedical Instrumentation
Answer» The CORRECT option is (c) THERMOCOUPLE For EXPLANATION: This arrangement is called thermocouple. The junction at a higher TEMPERATURE in thermocouple is termed as measuring junction. The junction at lower temperature in the thermocouple is called the reference temperature.
