Chapter 8
Identifying with Inductors
IN THIS CHAPTER
Inducing currents in coils with a changing magnetic field
Opposing changes in current with an inductor
Using inductors in filter circuits
Resonating with RLC circuits
Making frequencies crystal-clear
Coupling magnetic flux to transfer energy between circuits
Many of the best inventions in the world, including penicillin, sticky notes, champagne, and the pacemaker, were the result of pure accidental discovery. One such serendipitous discovery — the interaction between electricity and magnetism — led to the development of two amazingly useful electronic components: the induction coil and the transformer.
The induction coil, or inductor, stores electrical energy in a magnetic field and shapes electrical signals in a different way than does a capacitor. Whether operating alone, in special pairs known as transformers, or as part of a ...
