The device used to measure electrical current is the ammeter. An ammeter is specifically designed to measure the flow of electric current in a circuit, which is expressed in amperes (A). It is connected in series with the circuit in order to measure the current flowing through it accurately.

A voltmeter, on the other hand, measures voltage, which is the electrical potential difference between two points in a circuit. An ohmmeter measures resistance in ohms and is used to evaluate how much opposition a component presents to the flow of current. A capacitance meter measures the capacitance of capacitors, indicating how much charge a capacitor can store. Each of these devices has a distinct purpose, making the ammeter the appropriate choice for measuring current.
