| Student Manual | A thermistor is a semiconductor used to measure temperature. Its resistance depends on the temperature. The goal of the present experiment is to determine the resistance R as a function of temperature T. You are expected to come up with a mathematical model that can predict the temperature from the measured resistance. |
