A(n) __________ tester is used to check for a break in a wire.

• A. Voltmeter
• B. Ammeter
• C. Continuity tester
• D. Ohmmeter

Answer: (C)

A continuity tester is used to check for a break in a wire. It works by applying a small current through the conductor and indicating whether the path is complete. When the wire is intact, the circuit is closed and the tester sounds a beep or lights up. If there’s a break, the path isn’t continuous and there’s no indication. This makes it the quickest and most direct tool for confirming whether a wire is continuous.

Voltmeter measures voltage, not continuity. An ammeter measures current, not whether a path exists. An ohmmeter measures resistance and can be used to check continuity in some cases, but a dedicated continuity tester gives a simple yes/no indication specifically for breaks, which is exactly what you need here.
