FIELD: training appliances, possible use in laboratory practice sessions of physics course for studying physical laws and occurrences. ^ SUBSTANCE: exponential law of radioactive disintegration is modeled by means of integrating RC circuit, outputs of which are connected to inputs of voltage meter. Plant has base with image on face side of rectangle with label "particle counter", electric engine, moving bar with applied black rectangles of varying size, imitating amount of radioactive substance. On face side of base below rectangle with label "particle counter" first transparent window is positioned, imitating a vessel with radioactive substance. To the right from rectangle with label "particle counter" second transparent window is positioned for voltage meter. ^ EFFECT: possible visual modeling experiment using simple and cheap equipment without any possible threat to health. ^ 4 dwg |
