  • High School or College Physics


Day 2 of Linear Circuits.  Students spend more time working with voltage sources.  Problems are solved a couple different ways, each with a different ground location.  It turns out that the ground location in a circuit is not that important after all.

The material covers all of the lecture material from a second lecture in a traditional, sophomore-level linear circuits class.
