STUDENT LEARNING OUTCOMES 
 

General Objective

 This course will serve as a comprehensive study in alternating current ( AC circuits ). Student will be introduced to the principles, applications, and measurements of alternating current. Generally, students will begin their learning with AC measurements, then the use of AC measuring tools, and progressing into analyzing & troubleshooting various components commonly used in filter circuits, time constant operations, and resonant circuits. The course of study also includes transformer and relay operations and troubleshooting.
