How many questions are in this multimeter quiz?

This multimeter quiz has 25 questions.

Can you measure resistance on a live circuit?

No. Resistance should be measured with power off and stored energy safely discharged.

What does continuity check?

Continuity checks whether a low-resistance path is complete between two test points.

Before You Start

A multimeter is one of the most important beginner tools because it helps answer practical troubleshooting questions.

Simple pattern: Check voltage to see if power is present, continuity to see if the path is complete, and resistance to evaluate opposition to current flow.

Safety reminder: Resistance and continuity checks should be done with power off and stored energy safely discharged.

1. What does a multimeter measure?

Only voltage Electrical values such as voltage, resistance, and continuity Only temperature

2. What does voltage represent?

Electrical pressure Wire length Physical weight

3. What unit is used for resistance?

Volts Amps Ohms

4. Where should the black meter lead usually be plugged in?

COM V/Ω only The amp port every time

5. Before measuring resistance, the circuit should be:

Powered off Powered on Connected to a wall outlet

6. Why should you not measure resistance on a live circuit?

It can damage the meter or create unsafe conditions Resistance only works on AC The meter will always show zero

7. What does continuity usually tell you?

Whether a path is complete The exact voltage of a battery The age of a component

8. A continuity beep usually means:

The path is open There is a complete path The circuit has high voltage

9. No continuity beep usually means:

The path may be open or broken The wire is always good Voltage is too high

10. Voltage is usually measured:

Across a component or source Only with the probes touching each other Only after removing the meter leads

11. DC voltage is commonly found in:

Batteries Only wall outlets Only transformers

12. AC voltage is commonly found in:

Wall outlets AA batteries only Resistors only

13. If resistance is very high, current will usually:

Increase Decrease Stay exactly the same no matter what

14. If resistance reads near zero when it should not, this may indicate:

A possible short A perfect open circuit A dead battery only

15. If a meter displays OL while checking resistance, it often means:

Open loop or out of range Overloaded voltage is always present The probes are working perfectly on a closed circuit

16. When checking a capacitor with resistance mode, a reading that starts low and climbs can mean:

The capacitor is charging The meter is broken every time The circuit is definitely live

17. If a capacitor reads near zero resistance and stays there, it may be:

Shorted Fully normal in every case Measuring AC voltage

18. Before checking a capacitor, you should make sure it is:

Powered and energized Powered off and properly discharged Connected directly to AC power

19. What is one common beginner mistake with meter leads?

Leaving the black lead in COM Using the wrong port for the measurement Reading the display

20. If you are unsure which setting to use, the safest first step is to:

Guess and test live power immediately Stop and confirm the correct meter setting and safety steps Put both probes in the amp port

21. A good basic troubleshooting order for a device that will not power on is:

Check power, check connections, then check components Replace every part first Ignore voltage and only check the case

22. A 1.5V AA battery should read approximately:

1.5 volts DC 120 volts AC 0 ohms always

23. Resistance measures how much a component:

Opposes current flow Creates light Stores patient data

24. Why is continuity useful for checking wires?

It can quickly show whether the wire path is complete It measures exact battery capacity It automatically repairs the wire

25. What is the best description of a multimeter for beginners?

A tool for checking electrical conditions in circuits A tool only used for anatomy A tool that replaces proper training

What to Notice First

These cues help you connect the quiz questions to real multimeter troubleshooting.

Questions 4 and 19: Meter lead placement matters. Black usually goes in COM, and the red lead must match the measurement type.

Questions 5 and 6: Resistance checks are different from voltage checks. Resistance should be checked with power off.

Questions 7 through 9: Continuity helps determine whether a path is complete or open.

Questions 11 and 12: Batteries are DC sources. Wall outlets are AC sources.

Questions 16 through 18: Capacitors can store energy. They must be handled carefully and safely discharged before testing.

Question 20: The safest move is not guessing. Stop and confirm the correct setting and safety steps.
