Question

Answer the following question.

4. Thermistors measure temperature, have a nonlinear output and are valued for a limited range. So when a thermistor is manufactured, the manufacturer supplies a resistance vs. temperature curve. An accurate representation of the curve is generally given by a, +a, In(R)+ a; {In(R)}* + a; {In(R)}' where T is temperature in Kelvin, R is resistance in ohms, and a,a,,a,,a, are constants of the calibration curve. Given the following for a thermistor R. T ohm °C 1101.0 25.113 911.3 30.191 636.0 40.120 451.1 50.128 Approximate the value of temperature in °C for a measured resistance of 900 ohms.
