How is a basic continuity check performed?

• A. Use a voltmeter to check continuity.
• B. Disconnect the circuit and rely on visual inspection.
• C. Use a digital multimeter in continuity mode or resistance mode to verify a low-resistance path between two points.
• D. Continuity cannot be tested with a digital multimeter.

Answer: (C)

Continuity checks verify a complete, low-resistance path between two points. To perform it, first de-energize the circuit. Use a digital multimeter in continuity mode or resistance (ohms) mode. Place the probes on the two points to test; if there is a good path, the meter will usually beep and show a small resistance value (often a few ohms or less). If the path is open or highly resistive, you’ll see no beep or a high resistance reading. This direct method catches breaks that visual inspection can miss and confirms the actual electrical connection. Using a voltmeter isn’t a direct continuity test since it measures voltage, not path integrity, and it’s incorrect to say a digital multimeter can’t test continuity.
