Course Description:

This course covers the theory and application of magnetism, electromagnetism, the generation of electromotive force, AC and DC motor principles, transformer theory, types and applications. Students are introduced to electrical control circuits and the operation of a transistor. Students build on basic techniques and learn systematic troubleshooting methods and procedures to solve process problems. Analyzing motor control schematics and using advanced digital multi meters are stressed. Emphasis is on prevention and correction of energy wasting problems. 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.

Course Outcomes:

      1.  Describe principles of operation for AC and DC motors, circuit components, and conductors.

      2. Apply math and theory for alternating current calculation and values of voltage, current, frequency, capacitance, inductance and impedance.

      3. Describe various troubleshooting techniques of testing equipment as applies to AC power.

      4. Understand the relationship among voltage, resistance, and current values in circuits.

      5. Determine power and load requirements.

      6. Identify major components of electrical systems in circuits.

      7. Perform a variety of troubleshooting tasks using appropriate instruments/meters.

      8. Use schematics to trace electrical problems.

      9. Analyze motor control schematics.

    10. Wire and troubleshoot common motor control circuits.

Outcome Assessment Strategies:

  1. Intelitek on-line activities including end of section tests and final evaluation.
  2. Instructor generated evaluation including tests and projects.
  3. Hands on lab activities
  4. Hands on evaluation.
