Skin Effect in the Cylinder Conductor
V.I. Kozlov
Moscow State Lomonosov University
Physics Department

It is possible to investigate a skin effect in the cylinder conductor (wire) by the modification of its active resistance with the changing of the frequency of the flowing alternating current.
However thus modification is losing at the background of other factories, leading to the increasing of the losses of the energy in the measuring scheme. It is the laboratory work, in which the active resistance of the wire is finding with the special way, consisting in the using of the coil, winding in two wires. This circumstance permits to change the active resistance of the coil in two times at the invariably of its inductivity.

Two laboratory works on electrodynamics (circuit of constant and alternating current) with use of the personal computer are submitted. The program support is carried out with the help of universal system of modeling "Electronics Workbench 5.12" (EW). To works the methodical description of system EW is applied which is adapted to use in the educational programs. Is developed and within two years the computer testing is successfully applied at the admission and protection by the students of laboratory works. The programs for testing and practical work are placed on server of university "Dubna", that allows to organize remote training.
