Optical Black Box. Disk. RusPhO Final 2021
In this problem of the Final of RusPhO-2020, we need to measure the parameters of the cavity hidden inside the transparent disk. You can see the inscription “Final RusPhO 2020” on the box: the problem was originally developed for the 2020 olympiad, which did not take place due to the COVID pandemic. Оптический серый ящик …
Optical Black Box. Cube
This optical black box contains a mirror and a lens. We need to measure the lens focal length and determine how the mirror is positioned.
Black Box with a potentiometer
The 10-turn potentiometer is inside the black box featuring two outputs. We measure the resistance as a function of the handle angle of rotation and determine the wiring diagram.
Set of 4 electricity experiments
A set of four experiments with increasing difficulty, in which we should measure and interpret I-V curves. https://www.youtube.com/watch?v=mAWgILhu7EEhttps://www.youtube.com/watch?v=l9tY7N5Id14
Electric Motor
In this experimental problem, we investigate the electric motor using a frequency meter.
Heater Power
In this experiment, we measure the heat capacity of several objects using a heater and Dulong–Petit law.
Solar Cell
This experiment is about alternative energy. We study the LED and determine the solar battery efficiency.
Thermistor
В этой задаче исследуется резистор, сопротивление которого зависит от температуры. Нужно определить теплоемкость резистора, измеряя зависимость сопротивления от времени.
