A thermistor is being used to measure temperature. For a given resistance R the temperature is given by 1 In I, B T = degrees Kelvin R If To = 298 °K, B= 4000 and Ro = 20k2, calculate the temperature when resistance Ris 15k2. At this temperature, determine the rate of change of temperature dT/dR in °C/2.
