Relation between temperature and resistance of a conductor is ________

1.	Relation between temperature and resistance of a conductor is ________(a) Rt = Rref [1+t](b) Rt = Rref [1+α∆t](c) Rt = Rref [1-αt](d) Rt = Rref [1-t]The question was asked in class test.My doubt stems from Resistance Temperature Detector topic in section Transducers of Electrical Measurements
Answer» CORRECT choice is (B) RT = Rref [1+α∆t] To explain I would say: The RELATIONSHIP between temperature and resistance of a conductor is given by Rt = Rref [1+α∆t] where, Rt is the resistance of the conductor at t°C. Rref is the resistance of the conductor at reference temperature α is the temperature coefficient of resistance ∆t is the difference between the temperature being MEASURED and the reference temperature.
