When configured to measure current, how is a multimeter connected to a component?

• A. In series
• B. In parallel
• C. In tandem
• D. On the ground wire

Answer: (A)

When measuring current with a multimeter, it must be connected in series with the component whose current is being measured. This configuration ensures that all the current flowing through the component also flows through the multimeter. In a series connection, the multimeter acts as part of the circuit, allowing it to accurately measure the amount of current without altering the circuit's behavior. In contrast, a parallel connection would allow the current to flow through multiple paths, which could lead to inaccurate measurements or potential damage to the multimeter, as the internal resistance of the meter is very low, potentially causing a short circuit. The terms "in tandem" and "on the ground wire" do not accurately describe standard electrical measurement practices. Therefore, connecting a multimeter in series is the appropriate method for current measurement.
