What type of meter is used to check current in an electrical circuit?

An ammeter is specifically designed to measure the flow of electric current in a circuit, expressed in amperes (A). When connected in series with the circuit, it allows current to flow through the meter, providing a direct reading of the total current being utilized.

Using an ammeter is critical for assessing the performance of electrical systems, troubleshooting potential issues, and ensuring that components are operating within their specified current range. It is essential that an ammeter is correctly rated for the circuit it is testing to avoid overload and damage.

In contrast, other types of meters serve different purposes. A voltmeter measures voltage across two points in a circuit and is typically connected in parallel. A wattmeter assesses power consumption by measuring both voltage and current, while an ohmmeter evaluates resistance in a circuit. Each meter operates on different principles and serves distinct functions, thereby highlighting the specific role of the ammeter in measuring current.
