How should an inline ammeter be connected in relation to the device being checked?

An inline ammeter is designed to measure the current flowing through a circuit or device. To accurately measure the current being drawn by the device under test, the ammeter must be connected in series with that device. This configuration allows the entire current flowing through the device to pass through the ammeter, enabling it to provide a reading that accurately reflects the operational current of the device.

When connected in series, the ammeter does not divert or alter the flow of current, ensuring the measurement reflects what the device is actually utilizing during its operation. In contrast, connecting the ammeter in parallel with the device could create a short circuit, leading to erroneous readings and potentially damaging the ammeter or the circuit itself.

Thus, connecting the ammeter in series with the device being checked ensures both safety and accuracy in evaluating the electrical performance of that device.
