You interact with electricity everyday, but do you have an understanding of how it works and the principles involved? One of the of the most important tools you will use to understand electricity is Ohms Law. Named after George Simon Ohm who discovered it, Ohms Law describes the relationship between voltage, current, and resistance. To be more precise; "current is directly proportional to voltage and inversely proportional to resistance." This law can be a big help to you in everyday life. Using it you can determine how much current a household appliance will use and if using it will overload a circuit.

In this chapter you will learn about Ohms Law and how to apply it. You will also learn about AC current, and the role that capacitors and inductors play with it. You will also learn about electrical resonance, diodes, transformers, and power transformers.

To successfully complete this chapter you should...

  • Read chapter 18 in your text book (pages 369-392).
  • Carefully study the important concepts about electricity as you read the chapter.
  • Understand Ohms Law and how to apply it.
  • Be able to describe the role of capacitors and inductors in AC circuits.
