Which type of meter is used to measure current flow in a circuit?

An ammeter is specifically designed to measure the current flow in an electrical circuit. When measuring current, an ammeter is connected in series with the circuit under test, allowing it to read the amount of current (in amperes) flowing through that part of the circuit. This makes it essential for applications that require an understanding of current levels, which is crucial for troubleshooting and ensuring that existing circuitry is operating within safe and efficient parameters.

While a voltmeter is used to measure voltage across two points in a circuit and an ohmmeter is for measuring resistance, these devices serve different purposes than current measurement. A multimeter, while versatile and capable of measuring voltage, current, and resistance, often requires the user to switch settings to perform those different measurements. The most straightforward and dedicated instrument for current measurement in a circuit is indeed the ammeter.
