Eletrotecnia e Medidas I

Not applicable.

Theoretical/practical classes:
– Exposition of theoretical subjects, carried out with a combination of the expository method and the interpretative method, appealing to
student participation. Resolution of application problems in which the active participation of students is promoted.

Laboratory classes:
– The participatory method is followed, although other active methods are also used. Carrying out laboratory work with the support of
specific guides and presenting a report on the work carried out. Resolution of application problems in which the active participation of students is promoted.

The objective of the Electrical Circuits Theory and Measurements I curricular unit is to transmit to students the principles and basic notions
of Circuit Analysis concepts, in relation to direct current circuits and single-phase alternating current circuits and corresponding
measurements.
The expository method together with the resolution of theoretical-practical problems allows the student to know and understand the
operating principles of electrical circuits and measurement systems. Laboratory classes practically complement the knowledge and skills
mentioned above

– Direct current.
– Ohm’s Law.
– Association of resistors: resistors in series and resistors in parallel.
– Kirchhoff’s laws: mesh law and knot law.
– Voltage dividers.
– Current dividers.
– Independent mesh method.
– Superposition theorem.
– Nodal analysis method.
– Thévenin’s theorem.
– Norton’s theorem.
– Star-Triangle Transformation.
– Reviews on the use of complex numbers.
Capacitors and inductors: current voltage characteristic.
– Sine waves: period, angular velocity, frequency and phase lag.
– Impedance of a circuit.
– Circuits (RL), (RC), serial RLC.
– Active power, reactive power and apparent power.
– Introduction to Instrumentation.
– Measurement Equipment: Voltmeter; Ammeter; Oscilloscope; Oscilloscope Probe
– Static Characteristics of Measuring Devices.
– Measurement errors.

Periodic Assessment:

Two Periodic Assessments will be conducted, each worth 10 points (with a minimum of 40% in each assessment) on dates to be agreed upon with the students and the Course Director. The written Theoretical/Theoretical-Practical Periodic Assessments account for 60% of the final grade.

A laboratory component accounts for 40% of the final grade, and a minimum of 40% of the component (reports account for 20%; exam account for 20%) accounts for the final grade.

The laboratory component is subdivided into two parts:

. Laboratory work with weekly reports.

. A laboratory test.

The maximum number of absences in the laboratory is two.

To be approved in the Curricular Unit by Periodic Assessment, it is mandatory to obtain minimum grades in the laboratory component and in the Theoretical/Theoretical-Practical component.

Assessment by Final Exam (of all material taught):

Theoretical/Theoretical-Practical written exam, weighing 60% of the final grade and a minimum of 40% of the test score;

Laboratory component, weighing 40% of the final grade and a minimum of 40% of the component (reports weight: 20%; test weight: 20%) of the final grade.

The laboratory component is subdivided into two parts:

. Laboratory work with weekly reports;

. A laboratory test.

The maximum number of absences in the laboratory is two.

To pass the course, it is mandatory to obtain minimum scores in the laboratory component and the Theoretical/Theoretical-Practical component.

For students with student-worker status or equivalent (to be assessed), who must notify the course instructor of their status by the third week of classes, the attendance requirement for the laboratory component does not apply. In these cases, an alternative evaluation process will be established for the laboratory component, in agreement with the students.

The grades obtained are valid only for the current year.
