What type of current measurement is accomplished using an ammeter?

An ammeter is specifically designed to measure electrical current, which is the flow of electric charge in a circuit. When connected in series with the circuit, the ammeter allows the current to flow through it, providing a direct measurement of the amount of current in amperes (A). This tool is essential when assessing how much current is being consumed by various components in electrical systems.

Understanding the other types of measurements provides clarity on why the correct choice is focused specifically on current. Resistance measurements require a multimeter to be set to the appropriate mode and involve measuring the opposition to current flow. Voltage measurements, likewise, utilize a voltmeter to measure the electric potential difference between two points in the circuit. Power, on the other hand, is calculated using current and voltage, typically in the form of watts, but it is not measured directly by an ammeter. Thus, it is clear that the ammeter’s sole function is to quantifiably measure current in a circuit.
