IN THIS CHAPTER
Understanding current, voltage, power, and more
Comprehending electrical flow
Deciphering circuit diagrams
Amplifying your test score
When I was around 12 years old, I impressed my parents by taking an old television set apart and putting it back together. I impressed them right up to the point where I plugged it in and blew up the garage. But the world of electronics is a bit more complex than simply plugging something in and seeing whether it works. I (and the garage) learned this lesson the hard way.
Six years later, when I took the ASVAB, I scored very well on the Electronics Information subtest. (Go figure!) This subtest is designed to measure your knowledge of the principles of electricity and how these principles are applied in the real world. You may see questions about transistors, magnets, engines and motors, and radio and television. (Curiously, there are no questions on this subtest concerning the impromptu demolition of garages.)
You don’t have to be an electronics whiz to score well on this subtest. If you’re not familiar with this information and you want to pursue a military career that requires you to do well on this subtest, this chapter is calling your name. You also need to have some familiarity with basic mathematical and algebraic principles (see Chapters 6 and 7 for more information).
