We describe a set-up for measurement of the absolute zero by Johnson–Nyquist thermal noise which can be performed within a week in every high-school or university. Necessary electronic components and technical guidelines for the construction of this noise thermometer are given. The operating temperature used is in the tea cup range from ice to boiling water and in this sense the set-up can be given in the hands of every high school and university physics student. The measurement requires a… 


Determination of the Boltzmann constant by the equipartition theorem for capacitors
A new experimental set-up for measurement of the Boltzmann constant is described. The statistically averaged square of voltage U 2 is measured for different capacitances C. The Boltzmann constant is
A Boltzmann constant determination based on Johnson noise thermometry
A value for the Boltzmann constant was measured electronically using an improved version of the Johnson Noise Thermometry (JNT) system at the National Institute of Standards and Technology (NIST), USA, with a relative standard uncertainty of 5.5%.
Johnson Noise
An experiment was performed that determines the Boltzmann constant k and the centigrade temperature of absolute zero by measuring the thermal noise of resistors. The Nyquist theorem provides a
Determination of absolute zero temperature from thermistor voltage noise
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
Johnson noise thermometry
Johnson noise thermometers infer thermodynamic temperature from measurements of the thermally-induced current fluctuations that occur in all electrical conductors. This paper reviews the status of

Several consecutive experiments are described with a printed circuit board PCB set-up, especially designed for these experiments. Doing the consecutive experimental tasks opens up possibility to
Johnson Noise and Shot Noise
Two types of electrical noise fundamental to any circuit and their relation to fundamental constants are investigated. Johnson noise of a controlled-gain system is measured across different
