Basics of Electricity, DC Circuits

DCThis class is designed to introduce you to the DC (Direct Current) concepts of the basics of electricity.  No prior knowledge of electricity is required to attend this class.  All simple theories and concepts will be studied via practical hands-on exercises and demonstrations. 

The training will help answer any of the following questions which you may have:

  • What is a capacitor?
  • What is a resistor?
  • How do electrons travel in a wire?
  • What are the graphical symbols and what do they represent?
  • What is Ohm's law?
  • What is power, horsepower, and energy?
  • What is the difference between a parallel circuit and a series circuit?
  • What are KVL and KCL and how can I use them to troubleshoot a circuit?
  • What is permeability, µ, B-H curves and induction?
  • How does a simple DC generator function?
  • etc.

We understand your work is important to you and that you want the right training which meets your requirements. Therefore, we offer the flexibility to customize our training to address your specific needs.  Although a standard agenda is established for each class, on the first day of training, we will inquire you about your work, what you already know, and what you would like to learn so that we can tailor the class to your precise applications, as necessary. We want to provide you with the best, value-added training available, that is advantageous to you and to your organization.

Various Comments from Past Attendees

"I learned more in this class than any I've taken in years!...Excellent class / instruction - Thanks and I look forward to future classes."
Engineer - Sandia National Laboratories 

"Excellent course - Enjoyed the PC-based schematic exercises; they supported the hands-on portion very well....Great job, Jay"
Technologist - Sandia National Laboratories 

"Enjoyed having conversations on practical applications!"
Engineer - Sandia National Laboratories 

"Jay is an absolutely wonderful instructor (but I'm sure you already know that !).  I'm still amazed at how he was able to explain concepts I had never understood before (and he must have the patience of a saint to be able to answer all my silly questions !).  I will take more classes if I am able to get the opportunity."
Engineer - Sandia National Laboratories

"Very worthwhile course!"
Technologist - Sandia National Laboratories 

"Hands-on!  I know that we did it, and it really drives home the objectives, i.e. practical applications."
Technologist - Sandia National Laboratories
