2010-Resistance of a Thermistor (Rousseau & Tachjian)

From McGill University Physics Department Technical Services Wiki

The experiment consisted of measureing the resistance of a thermistor as a function of temperature. This was accomplished by applying a voltage across the thermistor via a custom built current source, whilst the thermistor was at a given temperature. The experiment was conducted for two negative coefficient thermistors. A characteristic value β of 3771.3 ± 0.3 K was found for thermistor A and a β value of 2869.0 ± 0.8 K was calculated for thermistor B. These values were charicterized with certainty for the temperature range of -50°C to +50°C.
