This course covers information on basic DC and AC electrical theory, definitions, basic component identification and analysis of series, parallel and combination circuits. Emphasis is placed on practical application, troubleshooting and problem solving. Students learn to troubleshoot common electrical problems in industry, such as low voltage, high voltage, open circuits, high resistance shorts to ground and current/voltage unbalance. Emphasis is on prevention of electrical energy waste. In order to legally do electrical wiring and some types of electrical troubleshooting, the State of Oregon requires that a person hold an appropriate Electrical License or Electrical Apprentice Card.
Recognize the relationship and the use of formulas to determine voltage, current, resistance and power.
Define terms; learn units of measurement, symbols and relationships.
Visualize and analyze series, parallel and combination circuits.
Identify and test using electrical measuring devices – analog meter; digital multi-meter; and oscilloscopes.
Investigate, troubleshoot and problem solve using electrical and electronic test instruments.
Use electrical schematics to troubleshoot electrical and electronic circuits.
Identify electrical waste and methods of electrical waste prevention.
