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…
Problem of the 8th Experimental Physics Olympiad, Skopje, 8 May 2021 Determination of Planck constant by LED
T. M. Mishonov, A. P. Petkov, M. Andreoni +5
This is the problem of the 8 International Experimental Physics Olympiad (EPO). The task of the EPO8 is to determine Plank constant using the given set-u…
The Day of the Inductance. Problem of the 7-th Experimental Physics Olympiad, Skopje, 7 December 2019
Todor M. Mishonov, Riste Popeski-Dimovsk, Leonora Velkoska +5
This is the problem of the 7-th international Experimental Physics Olympiad "The Day of the Inductance". A large inductance made by a general impedance converter is measured by the…
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…
Measurement of the Boltzmann constant by Einstein. Problem of the 5-th Experimental Physics Olympiad. Sofia 9 December 2017
Todor M. Mishonov, Emil G. Petkov, Aleksander A. Stefanov +5
Several consecutive experiments with specifically built set-up are described. Performing of the consecutive experimental tasks enables possibility to determine Boltzmann's constant…
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…
Measurement of the electron charge using Schottky noise. Problem of the 6-th Experimental Physics Olympiad. Sofia 8 December 2018
Todor M. Mishonov, Emil G. Petkov, Aleksander A. Stefanov +14
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…
