SPECIFIC AIMS The main objective of this course is to present the basic principles and foundations of Electricity and Electrical Machines to the Mechanical Engineering students. That is, to an audience composed of non-electrical engineering students. A second objective is to present the essential material in an uncomplicated fashion, focusing on the important results and applications, and presenting the students with the most appropriate analytical and computational tools to solve a variety of practical problems.
LEARNING OUTCOMES At the end of the course, the students should: 1. be able to use the fundamental techniques for the analysis of DC and AC circuits; 2. know the fundamental laws of electromagnetism, including the ability to analyze elementary magnetic circuits; 3. understand the basic operation principles of rotating electric machines ; 4. have practice with basic laboratory equipment: multimeters, oscilloscopes, power supplies and signal generators.
PREVIOUS KNOWLEDGE A previous knowledge on differential and integral calculus is required (from Mathematical Analysis I course).

Minimum attendance to the practical classes.
There are two evaluation components: 1. Component A: Individual performance analysis of each student in the laboratory (30%); 2. Component B: two intermediate examinations (70%). For students with a classification in component B greater or equal to 8.0, the final classification will be the average of component A (30%) and component B (70%); For students with a classification in component B smaller than 8.0, the final classification will be the classification of component B.
1 oral practical examination replaces component A; 1 two-hour written examination paper replaces component B.
