— Capacitor (4 pieces)
— 20 Ohm inductor coil
— Ferrite core
— Spool-hank (2 pieces)
— Methodological support
— Software for conducting computational modeling
— Storage system
The nominal values of the elements are selected in such a way as to ensure a noticeable difference in the natural frequencies of the oscillatory circuits assembled on their basis.
The entire set is supplied in a plastic storage system with a tray, which is closed with a transparent plastic lid with latches to ensure visibility of the contents.
Methodological support
The kit contains a methodological guide for conducting experiments, which contains instructions for performing 10 experiments on the assembled setups.
The kit also includes electronic methodological instructions for performing the modeling, which contain a description of all three blocks of the modeling program and descriptions of 2 calculation tasks (experiments) performed using each of the blocks of the calculation model.
Software for conducting computational modeling
The software for performing computational modeling consists of 3 blocks dedicated to modeling the processes of charging and discharging a capacitor, the start and stop of current flow through an inductor coil, and also modeling free oscillations in an oscillatory circuit.
