Unit 1. Getting Started in Electronics

To begin our study of electronics, we’ll start to get familiar with some common electrical components, and with some common instruments that technicians use to make measurements. We’ll also see that technicians must understand a number of electrical quantities, and they must know what units these quantities are measured in.

For any topic below with a Self-Test icon (which looks like this Self-test), click the icon to test your understanding of that topic. Self-Tests are for your practice only; no grades are recorded. The questions will appear in a new window. You may wish to resize this window so that you can read the questions more easily; then close the window when you’re finished with the questions for that topic.
