A meter will be used to measure a horn/strobe circuit's draw. Which one of the following is correct?

To accurately measure the current draw of a horn/strobe circuit, the meter must be connected in series with the circuit. This setup allows the meter to become part of the electrical circuit, enabling it to measure the flow of electric current directly. By doing so, the readings reflect the actual amount of current that is flowing through the device, which is essential for determining the circuit's performance and ensuring it operates within its required specifications.

Connecting the meter in parallel, on the other hand, is inappropriate for current measurements. When a meter is placed in parallel, it creates a short circuit, which not only risks damaging the meter but could also lead to hazardous electrical conditions. Hence, correct positioning is crucial for both safety and the integrity of the measurement being taken.

Furthermore, while it is prudent to disconnect the meter after testing to prevent any unwanted influence on the circuit, that action pertains to the procedure rather than the method of connection required for accurate current measurement. Connecting the meter in series ensures that it accurately captures the current flow during the test phase.
