1.	The resistance Rt of a metallic conductor at any temperature t is given by ___________(a) Rt = Ro(1+ɑt)(b) Rt = Ro(1-ɑt)(c) Rt = Ro(ɑt-1)(d) Rt = Ro(10+ɑt)I have been asked this question during an interview for a job.My doubt stems from Transducers for Body Temperature Measurement topic in section Physiological Transducers of Biomedical Instrumentation
Answer» The correct option is (a) Rt = Ro(1+ɑt) For explanation I would SAY: The resistance Rt of a metallic CONDUCTOR at any TEMPERATURE t is given by Rt = Ro(1+ɑt). Ro is the resistance at 0*C. ɑ is temperature coefficient of resistivity.
