The correct answer is “Polarity”—that is, which side of the circuit is positive and which is negative. That’s what you have to observe, but a voltmeter is commonly used to measure resistance, and that’s answer C. In studying for the exam, a future electrician will frequently encounter the directive “Use a voltmeter to measure resistance.” So when the question includes “voltmeter” and one of the answers is “resistance” the test taker’s brain immediately shouts, “Those go together!” And they do, but that’s not the question. “Pop knowledge” may be factually accurate and appear frequently in study materials, but it can still be a bad fit to the question posed.

The best way to answer a test question is, of course, to read the question carefully. But in addition, you must be aware of your brain’s tendency to serve up “pop knowledge” when you see key terms.

In a sentence: When you’ve prepared well, some ideas will be strongly associated, and when you see idea A, idea B will immediately come to mind, but that doesn’t mean idea B is the answer.
