Which device is used to measure electrical current?

The device used to measure electrical current is known as an ammeter. This tool is specifically designed to measure the flow of electric charge in a circuit, typically expressed in amperes. By connecting an ammeter in series with the circuit, it can provide an accurate reading of the current flowing through that particular path.

In contrast, a voltmeter measures the voltage across two points in a circuit, usually connected in parallel. An ohmmeter is used to measure resistance and is not capable of measuring current directly. Similarly, a capacitance meter measures the capacity of a capacitor and does not involve current measurement. Understanding the specific functions of each instrument is vital for effectively troubleshooting and analyzing electrical systems.
