7.1 DC Circuits

Textbook reading:

  • Walker Section 2.1, pages 725-728
    • You should know the “Definition of Electric Current, I”
    • Pay close attention to Example 12-1.  You should be able to work this example on your own.
    • Also, pay close attention to the water analogy in the section “Batteries and Electromotive Force,” figure 12-1


I’m using someone else’s video, because I had a hard time talking over a computer animation, and this guy got it to work.  Note, however, he often says “Potential Energy” when what he actually means is “Electric Potential Difference.” You can place a nice game of “spot the mistakes” with his video.

Your reading quiz will come from both the video and the textbook, so make sure you pay attention to both.
