## Learning Outcomes

After the course, the student will be familiar with the central concepts of electricity and thermodynamics.

In the first part of the course, they will be taught the fundamental quantities, units, and calculation formulas related to electrostatics and electric current. They will learn the most common electrical components and their main characteristics. They will learn how to solve problems related to direct current circuits using Kirchhoff's laws. They will understand why metals, semiconductors, and insulators conduct electricity differently. The student will gain an understanding of electrical power and learn to consider the temperature dependence in solving problems related to resistance, electric current, and electrical power. They will learn the basics of electromagnetism, providing insight into the natural laws governing electromagnetic phenomena. The course will teach a field-theoretical approach to describe force fields (electric, magnetic, and gravitational fields). They will learn to calculate the magnetic field generated by a straight current conductor and by a solenoid. Additionally, the student will learn to calculate the direction and magnitude of the magnetic force acting on an electrically charged particle in a magnetic field. Furthermore, electromagnetic induction will be studied with application examples.

In the second part of the course, they will learn about quantities and units related to thermal energy. They will gain an understanding of quantities, units, and natural laws related to heat storage, phase changes, and the behavior of gases. Examination of gases (thermodynamics) will lead to an understanding of the operating principles of heat engines (internal combustion engines, refrigerators, heat pumps).

In addition to theoretical studies, the course will include laboratory work, during which the student will become familiar with the phenomena and natural laws covered in the course through experimental measurements. They will learn to evaluate the accuracy of measurements and to perform thorough error calculations and analysis. The measurements result in two reports that will be evaluated.
