Course Description

An in depth study of Alternating Current (AC) electrical circuits. This course of study focuses on the math describing AC circuits, specifically the relationship between impedance, resistance, and reactance. Students will use these concepts to anticipate power factor and learn how to mitigate large inductive loads. Students will design, analyze, build, and test RLC circuits, inductance motor drivers, and filter circuits for audio signals. The lab work will focus on validating theoretical calculations by building circuits and testing them for expected performance. ADVISORY: ELEC A111. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

1. Students will be proficient at using electronic test equipment to measure and analyze the performance of AC circuits.
2. Students will be able to communicate the results of their analysis in a professional manner using industry standard schematics and report formats.
3. Students will be able to employ mathematical tools and fundamental laws to conduct analysis of complex AC circuits.

Course Objectives
