#### Course Description

Covers RLC circuits, transformers, AC power, and three phase power. Explores steady state sinusoidal analysis and phasor techniques. Introduces the Laplace Transform. Also incorporated is circuit simulation, math analysis software, and laboratory experiments to solidify classroom theory and practice. Prerequisites: ENGR 221 Audit available.#### Intended Outcomes for the course

Use appropriate circuit analysis techniques to analyze for AC and sinusoidal systems

Recognize and analyze 2nd order systems 85

Apply basic magnetic concepts to analyze magnetic circuit systems

Analyze power development and distribution systems

#### Outcome Assessment Strategies

Assessment methods are to be determined by the instructor. Typically, in class exams and quizzes, and homework assignments

will be used. Lab work is typically assessed by a lab notebook, formal lab reports, performance of experiments, and possibly a lab

exam.
