Which unit is used to measure electric current?

• A. Volt
• B. Ohm
• C. Ampere
• D. Farad

Answer: (C)

The unit used to measure electric current is the ampere. The ampere, often shortened to "amp," quantifies the flow of electric charge in a circuit. Specifically, one ampere is defined as the flow of one coulomb of charge per second. This measurement is foundational in electrical engineering and electronics, as it helps in understanding how much electric charge is moving through conductors, which in turn can affect the operation of circuits and devices. Other units, while important in their respective areas, measure different electrical properties. The volt measures electric potential, or voltage, while the ohm measures resistance in a circuit. The farad is used to measure capacitance, which indicates the ability of a component to store charge. Therefore, while each of these units plays a crucial role in the broader context of electricity and electronics, the ampere is specifically designated for measuring current.
