Course content
|
The course is an introduction to the study of electrical engineering. First, the basic concepts of electrical engineering are introduced, followed by the issue of electromagnetic wave propagation along lines and in free space. 1.Basic concepts of electrical engineering - Coulomb's law, electric charge, electrostatic field intensity, electric voltage, electrostatic field intensity. Electric current, current density, power and work of electric current 2. DC currents, source of electric current, Ohm's law, solution of linear circuits, Kirchhoff's laws 3.Methods of solving direct current circuits - simplification method, Kirchhoff equation method, loop current method, nodal voltage method. Methods for solving nonlinear circuits 4.Dielectric circuits - dielectric polarization, basic quantities and laws, Gaussian theorem of electrostatics, capacitance, Serial and parallel dielectric circuit, capacitor as an element of electrical circuit, transient 5.Magnetic circuits - basic quantities, Hopkinson's law, magnetic properties of substances 6.Induction law, phenomenon of self induction, phenomenon of mutual induction. Energy mag. field. Magnetization of the environment 7. Circuits in harmonic steady state - signal in steady harmonic state, simple passive dipoles in the circuit of harmonic steady signal, resistor, inductor (ideal coil), capacitor (ideal capacitor), composite circuits. Powers in the harmonic current circuit 8. Phasor diagrams. Resonant circuits - serial, parallel, resonant curve. Three-phase circuits 9. Double gates - reactance filters, attenuation and phase in the pass and impermeable frequency band 10. Communication line - line element, phasor diagram of line, voltage wave course, characteristic impedance of line, wave propagation along line, line of infinite length, short line, line empty, line of final length, reflection factor 11. Electromagnetic field - Maxwell's equations, Maxwell's shear current, first Maxwell's equation, second Maxwell's equation, basic relations describing the propagation of the electromagnetic field 12.Modification of Maxwell's equations for electrostatic, stationary current, magnetostatic, quasi-stationary and non-stationary fields 13.Solution of Maxwell's equations mag. vector potential.

Learning outcomes
|
The course provides to students with Maxwell's equations. Transmission lines, impedance, matching, reflections, standing waves.
Students are able to orientate in electrostatics, steady currents, static magnetic field, electromagnetic fields, Maxwell equations and wave propagation problems. They can analyze DC and AC circuits (transients and steady states).
