🔍 Key Concepts

• Voltmeter connection method in a circuit (series vs. parallel) • How meter range selection protects both the meter and the user • What happens if the selected range is too low for the actual circuit voltage

💭 Think About

• If you have no idea what voltage to expect, which range choice is safest for the meter and least likely to damage it? • Think about how a voltmeter is normally connected into a circuit: does it go in series interrupting the current path, or across (parallel to) the component? • What could happen to the meter or its fuse if you picked too small a range and the actual voltage was much higher?

✅ Before You Answer

• Remember that voltmeters are designed to be connected in parallel, not in series, with the circuit element being measured. • Check which choice best avoids overloading or damaging the meter when the circuit voltage is unknown. • Eliminate any option that would be unsafe or clearly not standard practice for using a voltmeter.

If the approximate voltage to be measured in an electric circuit is not known, what should be done?

use the lowest voltage range on the voltmeter

connect the meter in series with the circuit

only have to calibrate the meter before using it

use the highest voltage range on the voltmeter
