What type of measurement device is an ammeter used for?

An ammeter is specifically designed to measure electric current flowing through a circuit. It operates based on the principle of electromagnetic induction, allowing it to provide a direct reading of the current in amperes. When placed in series within the circuit, it captures the flow of electrons, offering gauge values that indicate how much current is being utilized. This measurement is crucial in diagnosing electrical problems, monitoring power consumption, and performing maintenance tasks, as understanding current flow is key to ensuring proper circuit functionality and safety.

In contrast, devices meant for measuring voltage are called voltmeters, while ohmmeters serve to measure resistance. Power measurement requires instruments like wattmeters, which integrate both current and voltage readings. Hence, the role of an ammeter is distinctly focused on current measurement.
