In an electric circuit, how is current measured using an in-line (series) ammeter?
A
Connect the ammeter in parallel across the component so it measures the voltage drop.
B
Place the ammeter near the wire without opening the circuit; it will measure current via the electric field around the conductor.
C
Connect the ammeter across the power supply terminals to measure the total available current without affecting the circuit.
D
Insert the ammeter in series so the same current flows through the meter and the circuit element being tested.
