Portland Community College | Portland, Oregon

Students will study fundamental electrical theory including series, parallel and series-parallel circuits, voltage, amperage, resistance, electromagnetism and circuit protection.  Fundamental theory, service and repair of battery and starting systems will be performed. Testing, diagnosis and repair of charging, starting, relay and basic circuits will be practiced in the classroom and laboratory using test boards and digital multi-meters. Students will study and practice various forms of wire splicing, repair and soldering techniques.

Upon completion of the course students should be able to:

• Perform basic electrical system inspection, maintenance, diagnosis, and repairs relating to basic electrical systems.
• Access and utilize repair information in a rapidly changing technology.
• Å·ÖÞ±­¾öÈü¾º²Âapp_Å·ÖÞ±­×ãÇòÍø-Ͷע|¹ÙÍø and implement strategies and processes to diagnose and repair electrical system problems.
