The aim of the course is to introduce the student to the theory of measurements and then to understand and analyze the electrical circuits with sine wave excitation at steady state. Also, evaluate and analyze three-phase circuits, magnetic circuits, the Fourier method and identify the transient behavior of the circuits. In the laboratory, the student will be able to handle basic electrical measuring instruments, become familiar with electrical components, and acquire skills in the assembling electrical circuits. Specific objectives of the course are for the student to be able to:
- Understand the measurement process.
- Recognize and interpret the characteristics of sine voltage, complex impedance and phasors.
- Solve circuits with sinusoidal excitation, using various methodologies.
- Recognize and interpret the advantages of the three-phase system and solve mathematical problems in three-phase circuits of all categories.
- Describe and explain the operation and structure of the transformer.
- Recognize the transient period of electrical circuits and solve related mathematical problems.
- Analyze and design basic electrical installations.
- Search, analyze and synthesize data and information, using the necessary technologies.
- Decision making.
- Independent work.
- Exercising criticism and self-criticism.
- Promoting free, creative and inductive thinking.

I. Written Final Exam (WE), which is in the form of problem solving with distinct difficulty and the free use of any book.
II. Evaluation of deliverable laboratory exercises (LE).
The course grade is derived from WE * 0.6 + LE * 0.4 and must be at least five (5.0).
The grade in each of the two assessment methods must be at least four (4.0).
The evaluation criteria are notified to the students through the course web page and also during the lectures.
