| Teaching Methods | |
|---|---|
| The course consists in front lessons (43 h), classroom exercises (12 h) for electrical network solving and activities in Lab (5 h) for electrical properties measurements for a total amount of 60 hours which are worth 6 credits. During the lessons the student is directly and interactively involved in the circuital problem solving. In this way also his learning evolution is monitored according to the already furnished skills. |
| Verification of learning | |
|---|---|
| THE ASSESSMENT OF THE ACHIEVEMENT OF THE OBJECTIVES WILL BE DONE THROUGH A WRITTEN TEST AND A SUBSEQUENT ORAL INTERVIEW. THE WRITTEN TEST TYPICALLY CONSISTS IN THE RESOLUTION OF TWO CIRCUITS, A SINGLE PHASE AND A THREE PHASE, TO BE PERFORMED IN TWO HOURS. TO GAIN ACCESS TO THE ORAL EXAM, THE STUDENT MUST DEMONSTRATE KNOWLEDGE OF THE PRINCIPLES OF KIRCHHOFF, THE BIPOLAR AND ELECTRICAL-NETWORK CONCEPT AND THE PRINCIPAL METHODS OF SOLVING STATIC OR PERMANENT SINUSOIDAL NETWORK. A LIST OF WRITTEN TESTS CAN BE FOUND AT HTTP://WWW.ELETTROTECNICA.UNISA.IT/DIDATTICA/DID_ETPROVEDESAME THE ORAL INTERVIEW TYPICALLY LASTS 20MIN. TYPICALLY, THREE QUESTIONS ARE PROPOSED TO THE STUDENT, ONE OF WHICH IS TO DEMONSTRATE A NETWORK THEOREM (TO TEST THE VISUAL AND DESIGN CAPABILITIES) AND TWICE TO HIGHLIGHT HIS ABILITY TO REASON ON THE ASPECTS OF INTEREST IN THE COURSE. THE FINAL VOTE IS EXPRESSED IN 30TH AND IS AN AVERAGE OF THE RESULTS ACHIEVED IN THE TWO TRIALS. IT WILL DEPEND ON THE DEGREE OF MATURITY ACQUIRED ON THE CONTENTS AND THE METHODOLOGICAL TOOLS OUTLINED IN THE COURSE, TAKING INTO ACCOUNT ALSO THE QUALITY OF THE WRITTEN AND ORAL EXPOSITION. IT IS ESSENTIAL TO KNOW THE PRINCIPLES OF KIRCHHOFF, THE BIPOLAR AND NETWORK CONCEPT, THE MAIN METHODS OF SOLVING STATIC LINEAR OR PERMANENT SINUSOIDAL NETWORKS, BOTH SINGLE-PHASE AND THREE-PHASE. THE STUDENT ACHIEVES THE LEVEL OF EXCELLENCE IF HE OR SHE IS ABLE TO FACE UNUSUAL OR UNEXPRESSED LESSONS LEARNED WITH AWARENESS. |
