Which multimeter switch position would you select to perform a continuity check?

• A. Ohms
• B. Volts
• C. Amps
• D. Diodes

Answer: (A)

Continuity means there is a complete, low-resistance path for current between two points. To test that with a multimeter, put the switch in the Ohms function. In this range the meter checks resistance and typically beeps if the path is good, signaling a closed circuit. A good path shows a small resistance value, while a broken path shows OL or a very high resistance. The other settings don’t test whether the circuit is continuous: volts checks potential difference, amps measures current (and could be unsafe or damage the tool if used on a live circuit), and diodes tests a diode junction rather than the overall continuity of a path. So the Ohms position is the correct choice for a continuity check. Remember to test with power removed and probe the two points you want to verify.
