The instrument that measures electrical current is the?

• A. voltmeter
• B. ohmmeter
• C. ammeter
• D. multimeter

Answer: (C)

The ammeter is the instrument specifically designed to measure electrical current flowing through a circuit. It operates by being connected in series with the circuit, allowing it to detect the amount of charge flowing through it. This measurement is expressed in amperes (A), which is the standard unit for electric current. In contrast, a voltmeter is intended for measuring voltage, or electric potential difference, across two points in a circuit, and it is typically connected in parallel. An ohmmeter is used to measure resistance in an electrical component or circuit, indicating how much opposition there is to the flow of current. A multimeter is a versatile device that can function as an ammeter, voltmeter, and ohmmeter, but when specifically identifying the instrument that measures only electrical current, the ammeter is the correct choice.
