Unit 9: Series-Parallel Circuits


In Units 7 and 8 you studied series circuits and parallel circuits. Many real-life circuits are more complicated, with combinations of both series-connected and parallel-connected components. In this unit we'll study such series-parallel circuits. You'll find that the basic rules of the game are the ones that you've already learned for series circuits and parallel circuits, but the job of applying those rules can get pretty tricky.
