To measure the current (amps) in a circuit using a digital multi-meter, it is essential to connect the leads in series between the power source and the load. This connection allows the multimeter to become part of the circuit, enabling it to measure the flow of electrical current. When current flows through the multimeter, it provides a direct reading of the ampere measurement for that specific circuit.

Connecting the multimeter in series ensures that all the current flowing through the circuit also flows through the meter, allowing for an accurate measurement. If the multimeter were connected in parallel or in other incorrect configurations, it could result in improper measurements or damage to the multimeter. Thus, the nature of how current flows necessitates this series connection for accurate readings.
