Basic physical quantities, fundamental forces, stationary charges – electrostatics, Coulomb’s law, superposition, electrical field, electric flow, Gauss’ law, area charge density, electrical potential and difference of potential, capacitor and the term “capacity”, charging process, polarization, moving charge – flow field, drift velocity, electrical current, Ohm’s law, electrical power, voltage- and current source, battery, impedance matching, power efficiency ratio, Kirchhoff’s circuit laws, linear direct current circuits, the term “magnetism”, magnetic field, magnetic flux, electromagnet, electrodynamic principle – Lorentz force, electric motor, cylindrical inductor and the term “inductivity”, Biot-Savart and Ampére’s circuital law, magnetization, magnetic excitation and magnetic flux density, matter in magnetic field and explanation of hysteresis curve, Lenz’s law, Faraday’s law, principle of a generator, harmonic alternating current, principles of alternating quantities, pointer diagrams, basic elements in alternating current circuits, power of alternating currents, impedance, transient processes in RC- and RL-elements, ODE of first order, complex variable domain, transformer, three-phase electric power, resonant circuit and mechanical analogy, two- and four-terminal network, measurement amplifier and control circuit, electric power and electromagnetic wave.

On successful completion of this module, students should be able to:

• analyze electric and magnetic fields, as well as the electric flux field, by utilizing Maxwell’s equations in integral form,
• calculate currents and voltages in DC and AC circuits,
• calculate transient switching events,
• illustrate the underlying principles of electrical machines (motor, generator, transformer),
• illustrate the basics of resonant circuits, measurement amplifiers and closed loop systems,
• calculate energy- and information transfer via electric lines and electromagnetic waves.
