Q: A meter used to measure the value of an unknown resistance is called a(n):
- ammeter.
- ohmmeter.
- voltmeter.
- None of the above.
A: ohmmeter.

Q: The ∞ symbol on an ohmmeter scale represents what?
- Low resistance.
- High resistance.
- High voltage.
- High current value.
A: High resistance.

Q: When reading an unknown voltage value, you should set the range selector position to __________.
- the lowest possible voltage range
- the lowest possible resistance range
- the highest possible ampere range
- the highest possible voltage range
A: the highest possible voltage range

Q: What should you do when using an ammeter?
- Hold the test probes tightly to the circuit component using your fingertips.
- Connect the meter in parallel with the power source to be sure it is working correctly.
- Connect the meter in series with the component to be tested.
- All of the above.
A: Connect the meter in series with the component to be tested.

Q: Which meter must be zeroed before use to assure accurate readings?
- The ohmmeter.
- The voltmeter.
- The ammeter.
- The DMM.
A: The ohmmeter.

Q: "Loading the circuit” with a meter means that when a voltmeter is connected across a circuit, the meter becomes "part of the load".
