 Comments on Test 3

  • Test 3 covers Chapters 19-22 except as indicated:  Omit the following sections: 19-8, 20-11.  Add:  18-7 (alternating current)
  • Review your notes and the Web notes.
  • Look over the homework.  Often test questions are slight variations of the homework.
  • Review the chapter summaries.
  • Equations and constants will be provided - but review what all of the symbols represent.  You will need to remember prefixes - pico, nano, micro, milli, kilo, mega, giga, tera.
  • Types of questions:  multiple choice, problems, definitions, descriptive (how does this work...)
  • Can you apply Kirchhoff's rules to a network of resistors and batteries?  Be able to apply the Lorentz force law (F = qE + qv x B).
  • Have you mastered the various right-hand and left-hand rules?
  • How do motors, generators, loudspeakers, transformers, ... work?
  • Phasor diagram for an RLC circuit ..., resonance
  • Recall the contributions of Oersted, Faraday, and Lenz.
  • Describe electromagnetic waves - drawings, equations for E and B, speed, names (radio, x-ray, ...), energy, intensity.
  • There will be one or two questions about the life and work of Nikola Tesla.  Video highlights are on the Web.
Here are some practice problems.
