Which device is used to measure electrical current?

The device specifically designed to measure electrical current is an ammeter. An ammeter is created to allow the flow of electric current through its measuring circuit and displays the amount of current in amperes. This direct measurement is essential for understanding circuit behaviors and diagnosing issues in electrical systems. In essence, the ammeter is dedicated to quantifying how much current is flowing at any given moment in a circuit.

Other devices, while related to electrical measurements, serve different purposes. A voltmeter measures voltage, which represents the electrical potential difference between two points in a circuit. An oscilloscope provides a visual representation of an electrical signal, allowing for analysis of its waveform, frequency, and amplitude over time. A multimeter can measure various electrical properties, including voltage, current, and resistance, but when specifically looking to measure electrical current, the function of the ammeter is the most direct and appropriate.
