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…
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…
Master equation for operational amplifiers: stability of negative differential converters, crossover frequency and pass-bandwidth
T. M. Mishonov, V. I. Danchev, E. G. Petkov +5
The time dependent master equation from the seminal article by Ragazzini, Randall and Russell [J. R. Ragazzini, R. H. Randall and F. A. Russell, "Analysis of Problems in Dynamics b…
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…
