Objectives
THE COURSE PROVIDES THE BASIC METHODOLOGICAL TOOLS FOR THE STUDY OF ELECTRICAL AND ELECTRONIC CIRCUITS.

KNOWLEDGE AND UNDERSTANDING.
CHARACTERISTICS OF BAISC COMPONENTS. METHODS AND TECHNIQUES FOR ANALYSING LINEAR TIME INVARIANT CIRCUITS.

APPLYING KNOWLEDGE AND UNDERSTANDING.
AT THE END OF THIS COURSE, STUDENTS WILL BE ABLE TO:
• SOLVE FOR CURRENT, VOLTAGE, STORED ENERGY, AND POWER IN LINEAR TIME INVARIANT DC CIRCUITS USING THE FOLLOWING TECHNIQUES: KIRCHHOFF’S CURRENT AND VOLTAGE LAWS, SUPERPOSITION, NODE VOLTAGE ANALYSIS, MESH CURRENT ANALYSIS AND SOURCE TRANSFORMATIONS;
• DETERMINE THEVENIN AND NORTON EQUIVALENT SOURCES;
• ANALYZE AND DESIGN LINEAR TWO PORTS, INCLUDING CONTROLLED SOURCES VOLTAGE;
• CALCULATE VOLTAGE, CURRENT, POWER AND ENERGY STORED IN LINEAR TIME INVARIANT AC CIRCUITS BY EMPLOYING PHASORS.
Prerequisites
KNOWLEDGE ABOUT THE SOLUTION OF SYSTEMS OF OF ALGEBRAIC LINEAR EQUATIONS AND DIFFERENTIAL EQUATION OF THE FIRST ORDER IS REQUIRED.

EQUIVALENT GENERATORS. POWER IN SINUSOIDAL STEADY STATE. REACTIVE LOADS. MAXIMUM POWER TRANSFER. POWER FACTOR CORRECTION.
Teaching Methods
THE COURSE INCLUDES CLASSROOM LECTURES AIMED AT PRESENTING THE THEORY AND NUMERICAL EXCERCISES TO STRENGTHEN THE OPERATIONAL SKILLS. THE EXERCISES ASSIGNED TO STUDENTS ARE SOLVED IN CLASS BY THE TEACHER USING THE TECHNIQUES PRESENTED IN THEORY LECTURES. THE EXCERCISE IS LED BY THE TEACHER TO DEVELOP THE PUPIL'S ABILITY TO IDENTIFY THE MOST APPROPRIATE SOLUTION TECHNIQUES AND PRESENT THE RESULTS IN A CLEAR AND EFFICIENT WAY.
Verification of learning
AN EXAM COMPOSED OF A WRITTEN AND AN ORAL TEST IS EMPLOYED TO ASSESS THE ACHIEVEMENT OF THE LEARNING OBJECTIVES. A MININUM GRADE OF 18/30 HAS TO BE OBTAINED AT THE WRITTEN TEST TO PROCEED TO THE ORAL EXAM.

- THE A WRITTEN TEST IS DESIGNED TO EVALUATE THE OPERATIONAL CAPABILITIES IN SOLVING CIRCUITS (MAINLY LINEAR DC AND AC CIRCUITS).
- THE ORAL EXAMINATION IS AIMED AT VERIFYING THE LEVEL OF THE THEORETICAL KNOWLEDGE AND SKILLS GAINED BY THE STUDENT.

THE FINAL SCORE (MIN 18/30, MAX 30/30 PLUS LAUDE) WILL DEPEND ON THE SCORES ACHIEVED IN THE WRITTEN AND OTAL TEST. THE EXAMINER MAY DECIDE WHETHER PARTICULAR STRENGTHS AND WEAKNESSES COMPENSATE EACH OTHER.
