Base Knowledge
Circuit Theory 1, Mathematics and Physics
Teaching Methodologies
In theoretical and theoretical-practical classes, a theoretical exposition is made, in active interaction with students, of each subject, which is immediately complemented by the resolution (individual or group) of examples of application of knowledge for consolidation.
Learning Results
At the end of the UC, students must be able to:
- Distinguish between single-phase and polyphase systems;
- Analyze (explain and solve) three-phase (balanced) sinusoidal alternating current electrical circuits (with star and/or delta connections);
- Analyze (explain and solve) three-phase (unbalanced) electrical circuits of sinusoidal alternating current (with star and/or delta connections);
- Determine the characteristic damping factor and resonant frequency of RLC circuits in series or parallel;
- Calculate the quality factor of a network and the bandwidth of a network;
- Use frequency and amplitude scaling techniques;
- Calculate the complete response (natural and forced) of RLC circuits
- Explain the phenomenon of resonance and relate it to possible practical applications
- Dimension (calculate) the elements necessary to correct the power factor
