Temperature transducers make use of ___________(a) change in resistivi

1.	Temperature transducers make use of ___________(a) change in resistivity(b) change in length(c) change in area(d) change in capacitanceI have been asked this question in an interview for internship.I'd like to ask this question from Transducer Selection Factors in section Transducers of Electrical Measurements
Answer» The CORRECT choice is (a) CHANGE in resistivity Explanation: The change in resistivity of the material of a conductor is used to MEASURE the variation in temperature. Temperature is affected due to change in the resistance which in TURN VARIES the resistivity.
