A thermistor is placed in a 100 deg c environment, and its resistance is measured as 20,000 ohms. The material constant, beta , for this thermistor is 3650 deg c. If the thermistor is then used to measure a particular temperature, and its resistance is measured as 500 ohms, determine the thermistor temperature.
