Course review:
0. Work safety, effects of electric current on human organism, injury by electric current, protection of live and dead parts of the electric device, first aid for injury by electric current, fire protection. 1. Electrostatics - experiments with Van de Graaff generator. 2. Electric current in metal (wire resistance, the dependence of electrical resistance of metallic conductors on its geometrical dimensions, material and temperature), Ohm's law. 3. Electric current in an electrolyte (electrolysis, lead-acid battery). 4. Electric current in gas (non-independent and independent electrical discharge in a gas at normal pressure, discharge in a dilute gas, Ruhmkorff's transformer). 5. Electric current in a semiconductor (diode current-voltage characteristic). 6. Stationary and non-stationary magnetic field Oersted experiment with conductor current in a magnetic field, the stationary magnetic field of a permanent magnet, coil and Helmholz coils. Lenz's rule, Foucault currents (Waltenhof pendulum). 7. Vibration of the electromagnetic oscillator (demonstration of damped oscillations of electromagnetic oscillator, phase shift current to voltage, electromagnetic coupled oscillators). 8. Geometric optics - light reflection from flat, concave and convex mirrors, refraction and total reflection of light, the passage of the light beam lens. Refraction from air to water. View the subject through mirrors and lenses. 9. Wave optics (decomposition of light by a prism, interference of light, Yong experiment, Newton glass), bending light (slit, thin fiber optic grid). 10. Experiments with kit Gamabeta.
