Eletrotecnia e Medidas I

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.

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.
