Learning Outcomes
In this course, the student will study the most important quantities, units, phenomena and natural laws related with electrical engineering. We will go through the quantities, units and components of electrostatics, as well as the physical properties of the electrostatical components from a technical point of view. The student will study the definition of the magnetic flux density, and they will learn how it can be generated in electrical engineering. We will study the forces yielded by the magnetic flux density of point charges and on current-carrying conductors. The student will understand the technical mechanisms that are used in generating induced emf in the dynamo of a bicycle, in wind generator and in water generator, as well as in the steam turbine of a nuclear power plant. Related with the induced emf, we will study the principle of an ideal current transformer. The induced emf will lead us logically to the concepts of alternating voltage and current.
Student's Workload
