Determination of absolute zero temperature from thermistor voltage noise
© 2020 European Physical Society. We present a simple experiment to determine absolute zero temperature by measuring the Johnson noise of a thermistor. Using the thermistor itself as a temperature sensor, we measure the thermistor voltage noise at different temperatures by submerging the thermistor...

We present a simple experiment to determine absolute zero temperature by measuring the Johnson noise of a thermistor. Using the thermistor itself as a temperature sensor, we measure the thermistor voltage noise at different temperatures by submerging the thermistor in hot and cold water contained in a thermally insulated cup.
