Basics of Electricity, AC Circuits

ACThis class will introduce you to the AC (Alternating Current) concepts of the basics of electricity.  No prior knowledge of AC 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:

  • How do I measure or calculate the impedance in an AC circuit?
  • What is frequency, period, phase, etc?
  • What is the Q of a coil? Should it be high or low?
  • What are the different types of capacitors and how would I select a particular type?
  • What exactly is Power Factor, about which I've heard a lot lately?
  • What is an autotransformer?
  • What is an unbalanced 3-phase load? How can I balance it?
  • What is the Q of a tank circuit? For that matter, what is a tank circuit?
  • How do I calculate the time constant of an RC circuit?
  • How do I use my voltmeter, ammeter, ohmmeter, multi-meter, LCR meter, etc?
  • etc.
