Which instrument measures electric current (amps)?

Explanation:
Measuring electric current focuses on how much charge passes a point per second, which is reported in amperes. An ammeter is built specifically to quantify that flow and is connected in series so all the current goes through it, giving a direct reading of the current in amperes. A voltmeter, on the other hand, measures voltage and is connected in parallel across a component. An ohmmeter determines resistance by applying a known current and reading the response. A multimeter can measure multiple quantities, including current, but only when set to current mode and used correctly; the dedicated instrument for current is the ammeter.
