The clamp-on meter allows the circuit to stay ______ and the meter to be positioned anywhere.

The clamp-on meter allows the circuit to stay ______ and the meter to be positioned anywhere.

• A. Incomplete
• B. Open
• C. Complete
• D. Paused

Answer: (C)

Clamp-on meters read current by surrounding a single conductor with a magnetic core. They don’t need to break the circuit, so the electrical path stays closed and current continues to flow. Because the measurement relies on the magnetic field around that conductor, you can position the clamp anywhere along the wire and still get an accurate reading, as long as only one current-carrying conductor is inside the clamp. That’s why the best fit is “complete”—the circuit remains closed, unlike the other options which imply an interruption or pause in current.
