Lectures

  • Semester 6, position 1

Goal

The aim of the course is to familiarize the students with basic laws of electrical engineering and to develop their competence for acquisition of more advanced academic knowledge and skills in scientific, professional and applied areas of mechanical engineering relying on electrical engineering. The students are introduced into basic phenomena, devices and circuits encountered in electrical engineering, and methods for their analysis and basic measurements.

Outcome

Upon successful completion of this course student should be able to: 1.theoretically and mathematically describe and incorporate basic concepts, laws, relations and processes of general electrical engineering, i.e., area of electrostatic, electrokinetics, electromagnetism and alternating (sinusoidal) currents; 2.mathematically adequately describe expresses and coupling the various electrical, magnetic, and other physical quantities required for basic engineering modeling of different phenomena and processes in electrical engineering; 3. theoretically and mathematically describe and link the basic concepts in the field of electrical measurements; 4. analyze and engineeringly display the results of direct and indirect laboratory measurements. 5. recognize the connection of mechanical, hydraulic and thermal systems with analogue electrical systems. Checking of outcomes referred to in points 1), 2), 3) and 5) is carried out through the questions on tests, colloquiums and final exam, or checking student responses to questions. Outcome point 4) is checked by an individual laboratory exercises and the defense of student reports made after the laboratory exercises.

Theoretical teaching

Electrostatic (brief historical overview, electrical load, Coulomb's law, electric field, potential and voltage, conductors in an electric field, Gauss's law with applications, dipoles, polarization of dielectrics, capacitors: capacitance, type and application, energy of the electric field); Direct current (current field and its characterization, electrolysis, continuity equation and Kirchhoff's laws, Ohm's law, Joule's law, resistors, ems (electromotive force): its origin and type, electric generators: characteristics and transformation, electric circuits and networks, work and power, basic theorems of electrical circuits); Electromagnetism (magnetic field, basic quantities and laws, concept of magnetic flux and conservation law, Ampere's law on the circulation of the vector of magnetic induction, the materials in the magnetic field, magnetisation field and total current law, the magnetic circuits, electromagnetic induction, inductance coefficients, energy of magnetic field, electromechanical conversion); Alternating (sinusoidal) current (generation, characterization, phasor's approach, power, network analysis methods in steady sinusoidal state); Three-phase circuits.

Practical teaching

The selected problems will be solved on auditory exercises. Six laboratory exercises are scheduled: 1. Introduction to basic electrical measuring instruments and principles of their operation. Practical application. 2. Basic measuring in DC circuits: current, voltage, power and resistance. 3. Demonstration of basic electromagnetic's laws and proofing of them by measuring. 4. Basic measuring in AC single phase circuits: current, voltage, power, inductance, capacitance and resistance. 5. Three phase power measurements. 6. Advanced techniques in electrical measuring: digital and computer based measurements.
