Set-up for observation thermal voltage noise and determination of absolute temperature and Boltzmann constant
Todor M Mishonov, Nikola S Serafimov, Emil G Petkov +1
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 electr…
Tunable High-Q Resonator by General Impedance Converter
T. Mifune, T. M. Mishonov, N. S. Serafimov +6
For the need of measurements focused in condensed matter physics and especially Bernoulli effect in superconductors we have developed an active resonator with dual operational ampl…
Simple do-it-yourself experimental set-up for electron charge measurement
T. M. Mishonov, E. G. Petkov, N. Zh. Mihailova +6
A simple experiment for the electron charge measurement is described. The experimental set-up contains standard electronic equipment only and can be built in every high-schoo…
Probability distribution function of crossover frequency of operational amplifiers
Todor M. Mishonov, Vladimir G. Marinov, Victor I. Danchev +7
For the first time the cumulative distribution function of the crossover frequency of a contemporary operational amplifier ADA4898-2 is experimentally studied. Using a USB Lock-In…
Determination of Boltzmann constant by equipartition theorem for capacitors
T. M. Mishonov, V. N. Gourev, I. M. Dimitrova +4
A new experimental set-up for Boltzmann constant measurement is described. Statistically averaged square of voltage is measured for different capacitances . B…
