Basic Circuit Troubleshooting and Testing CEU



PRICE: $50 for ESA members / $70 for Non-Members 

This two-hour online course provides students an overview of how to fix what is found inside a faulty panel. Review the types of circuits and the common causes of circuit faults, and take an in-depth look at how to locate the sources of circuit faults. After completing this course you will be able to:

  • Describe the different types of circuits
  • Explain the characteristics of a circuit in a normal state
  • Describe the common causes of circuit faults
  • Describe how to determine a circuit fault
  • Identify the process of locating the source of a circuit fault

What to Expect in the Online Course:

The course is delivered using a presentation style that is built off the exact same content covered in our instructor led course.  The presentation includes text,audio, graphics, videos and activities to help you absorb the information presented. This course has a short quiz at the end which you will be required to pass with a 70% or greater to complete the course.
