The video lessons feature lively animation, and the engaging text lessons make it easy to spot the key terms for a given topic by using bold print. These major components are also likely to show up in the practice quizzes that go with each lesson.
Objectives of the ASVAB: Power, Devices & Computers Chapter
The ASVAB is concerned with finding out whether the examinee has the required aptitude to join the military. This chapter will help you with some questions that you could be asked when you reach the Electronics Information subtest. The length of this subtest reaches 16 multiple-choice questions if you take the computer version, and 20 questions are featured on the paper version of the exam.
1. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy
Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.
2. What is Electric Power?
Power is a word we use all the time, but do you really know what it means? We'll look at how electrical power relates to voltage, current and resistance and how knowing that relationship can help you in everyday life.
3. Comparing Analog & Digital Devices
What is the difference between analog and digital signals? Learn some examples of analog and digital devices, and how we convert between the two types of signals.
4. Binary Language of Computers: Definition & Overview
All digital data used in computer systems is represented using 0s and 1s. Binary coding systems have been developed to represent text, numbers, and other types of data.
