Reading Summary /next exam Chapter 18 Parallel Plate Capacitor (548) Chapter 19 Sections 19.1-19.4 Section 19.5 – Only what we cover in class Chapter 20 Section 20.1-20.4 Section 20.6-20.11 Section 20.12 – A covered in clss You might want to review the problem on the next slide as an example of the type of question that could pop up. It probably won’t, though.

A portable CD player operates with a voltage of 4 A portable CD player operates with a voltage of 4.5 V, and its power usage is 0.21 W. What is the current in the player?
