In this chapter, we will begin our study of inductors and coils.

20.1 Inductors, Coils, and Magnetic Flux

In Chapter 16, we learned that capacitors stored charge by using an electric field. We also learned that capacitors continued to hold their charge even after they were disconnected from the rest of the circuit. We learned in Chapter 19 that capacitors blocked DC signals but allowed AC signals to pass through.

20.1.1 What Is an Inductor?

An inductor is kind of like the capacitor’s evil twin. It behaves in some ways that remind us a lot of capacitors, but it is operating on a different aspect ...
