How do you check continuity?

• A. Ohmmeter
• B. Ammeter
• C. Voltmeter
• D. Megger

Answer: (A)

Continuity is about whether there is a complete conductive path between two points. To verify it, you use an ohmmeter, which applies a small test current and measures resistance. If the path is continuous, the resistance reads very low (often near zero) and may even beep, confirming the connection. If there’s a break, you’ll see a very high or infinite resistance, indicating an open circuit. A voltmeter measures voltage, not whether a path exists. An ammeter measures current and requires a powered circuit; it doesn’t directly tell you if a path is continuous. A megger tests insulation resistance by applying high voltage, which is for checking insulation quality rather than confirming a direct conductor connection.
