Objectives
• Understanding of voltage, current, and power and ability to calculate these quantities in both time-invariant and time-variant cases;
• Stationary and moving charges generate fields, these in turn generate voltages and currents in devices and circuits, understanding of these contexts;
• Understanding of simple electronic devices.
Subject Chapter 1
* The electrostatic field (Coulomb's law and electric field, potential and voltage, electric flux density and dielectric polarization, capacity, energy content);

• Steady-state electric flow field (current and current density, resistance and Ohm's law, energy and power);
• Simple electric networks (reference arrows, ideal voltage and current sources, Kirchhoff's laws, resistive networks, real voltage and current sources, superposition principle, meshes and nodes);
• Mechanisms of current conductance (vacuum, gases, liquids, semiconductors);
• Steady-state magnetic field (force in magnetic field, current generates magnetic field, magnetic potential difference, magnetic flux, magnetic polarisation, magnetic circuit, inductance);
• Time-variable electromagnetic field (law of induction, mutual inductance, energy content, induction in stationary and moving coils).

Chapter 2
* Introduction (summary of voltage-current relations of components of chapter 1, characteristics of periodic quantities);

• Alternating voltage and current (phasor diagram, complex analysis, voltage divider, resonance, locus diagrams, energy and power);
• Time-variable periodic signals of arbitrary waveform (frequency mixture, harmonic analysis, Fourier series applied to circuit analysis);
• Switching transients in simple electric networks (networks with one energy storing component connected to DC voltage, networks with one energy storing component connected to AC voltage, networks with several energy storing components).

Chapter 3
*Electronic components (diodes, bipolar transistor, field effect transistor);

• Electronic basic circuits (rectifier, circuit analysis with nonlinear components, load line, transistor switch, transistor amplifier).

Supplement
* Accidents (What is dangerous? How do you respond in case of emergency? Safety rules).
