In Chapter 2 of this minibook, you learn that you can measure voltage with a voltmeter. You can also use meters to measure many other quantities that are important in electronics. Besides voltage, the two most common measurements you’ll need to make are current and resistance.

Rather than use three different meters to take these measurements, it’s common to use a single instrument called a multimeter. Figure 3-9 shows a typical multimeter purchased from RadioShack for about $20.
