How is an ammeter connected to measure circuit current?

  2. Clamped to the neutral conductor only
  3. In series, placed in a gap in the circuit
  4. Between the circuit and ground

Correct answer: In series, placed in a gap in the circuit

The current must flow through the meter, so the meter becomes part of the circuit path.
