The course introduces the basic principles governing the behavior of electronic circuits. Throughout the course, students study fundamental circuit components: voltage sources, current sources, resistors, capacitors, and inductors, as well as the theorems and analysis methods used to solve various circuit topologies. First, the physical foundations of electronics, electrical quantities, and basic circuit laws are introduced. Then, methods for DC circuit analysis with resistors are covered, including practical aspects (materials, coding, resistor types, values, tolerances). Later, passive components such as capacitors and inductors are studied and transient analysis of RC and RL circuits is introduced. Finally, alternating current (AC) is studied, covering its characteristics, fundamental parameters, and the analysis of linear circuits under sinusoidal signals, including the use of phasors and impedance. The course establishes the basis for understanding complex electrical phenomena and developing skills for more advanced electronics courses. Practically, students perform labs to learn basic electronic instrumentation and implement circuits supporting theoretical concepts.

The objectives of this course are:
- Understand passive electronic components (resistors, capacitors, inductors) and their behavior in DC and AC circuits, including transient RC and RL phenomena.
- Develop the ability to analyze linear electrical circuits using fundamental methods and theorems, interpreting quantities such as current, voltage, impedance, and phase shift.
- Become familiar with laboratory instruments and procedures, using equipment (power supplies, multimeters, oscilloscopes, signal generators) to characterize components and verify circuits.
- Integrate analysis, assembly, and verification skills to connect theoretical models with experimental results.

The course is taught weekly with five 50-minute sessions. The methodology combines lectures with hands-on exercises that illustrate the concepts explained, and continuous assessment exercises that students must complete both in and out of class. The content covered in the lectures is reinforced with practical sessions primarily dedicated to hands-on work with electronic instruments and circuits, where students work in pairs. One of these practical sessions is divided into two parts: first, a flipped classroom session using the Picoscope portable instrument, which is provided to the students; and then, individually at home, designing and implementing phase-shifting circuits with this instrument and a breadboard. Some sessions are dedicated to individual assessment through written tests or review sessions.
The procedure for each practical session is described below:
• The instructions are published on eStudy in advance of the practical session.
• Students are given two weeks to complete the practical exercise outside of class time.
• One of the students in the group deposits the submission in a designated area on eStudy.
The assessment elements for this subject are exams: mid-term, final (regular and extraordinary sessions), continuous assessment exercises (completed in and out of class) and laboratory sessions.
The following criteria are used to assess the quality of student performance in relation to each learning outcome. Each criterion defines what is being evaluated, how it should be demonstrated, and what aspects constitute correct and complete work.
RA.1 – Knowledge of basic electronic components
The student demonstrates:
1. Understanding of direct current and basic circuit analysis theorems.
2. Identification and knowledge of the behavior of resistors, capacitors, and inductors.
3. Understanding of alternating current principles and the response of AC components (reactance and impedance).
RA.2 – Ability to analyze electronic circuits
The student is able to:
4. Analyze DC circuits using systematic methods and circuit theorems.
5. Solve circuits with reactive elements, distinguishing between transients and steady-state operation.
6. Analyze AC circuits using phasors and interpret the results physically and coherently. 7. Present problem-solving procedures clearly and justify conclusions.
8. Implement and verify simple passive circuits using laboratory instrumentation.
9. Interpret and integrate theoretical and experimental results, working effectively in a group and demonstrating autonomy in individual parts of the experiment.
