Chapter Three, "How Does Electricity Work?," examines why electricity produces heat and how heat is generated by a current. Concepts introduced are the Joule, infrared rays, inductance, and magnetic fields. The text pages look in detail at the Joule, thermal heat, electromagnetic waves, and magnetism.
Chapter Four, "How Do You Create Electricity?," starts off by looking at generators and the way they create electricity. Then it moves on to batteries and other sources of power. These sources include chemical cells, water and fuel cells, as well as dry batteries. You will even learn how to create a coin battery on your own. The text portion discusses thermal power generation, nuclear power, hydroelectric, and wind power generation.
Chapter Five, "How Can You Conveniently Use Electricity?," looks at how people use electricity and how some consumer electronic products work. Here you will see what a semiconductor is and how they are put together. You will examine diodes and transistors and the way they are used to create everything from Christmas tree lights to large outdoor displays. The text finishes up with additional topics like converters and inverters, sensors, and optical sensors.
There is a lot to like about The Manga Guide To Electricity. First and foremost is that it makes learning about electricity fun. It assumes that you have no real background in the subject, but by the end will give you a solid basic understanding of electrical theory. It also provides a good understanding of how electricity works from a larger perspective as well.
Because electricity is so important to our lives, and because it is something that is not really taught in schools except to a very small percentage of students, I think this is a very good book in which almost anyone will gain a better understanding to how electricity powers our lives. For this reason, I say The Manga Guide To Electricity is a must read.
