To connect an ammeter into a circuit, the ammeter should be

Measuring current requires the device to be in the same path as the circuit flow, so the ammeter must be connected in series with the circuit. When placed in series, all the current that passes through the load also flows through the meter, giving an accurate reading of the circuit current. If the meter were connected in parallel, it would create another path with low resistance, shunting current away from the load or significantly altering the circuit, which leads to an incorrect reading and potential damage. Therefore, the correct approach is to place the ammeter in series, and in practice the meter should have very low internal resistance to minimize voltage drop while still providing a readable measurement.
