AC Generation

Where does voltage come from?  How do we get it?  Thanks to people such as Michael Faraday and Joseph Henry we now have an idea how to harness the energy that was once attributed to the gods.

Learning Objectives

  • Explain electromagnetic induction
  • Describe the difference between a simple alternator and practical alternator
  • Discuss how a waveform is generated
  • Analyze a waveform and determine how effective, instantaneous, and average values are calculated
See the AC Generation section of the Appendix for worksheets that can be used in this section.
