Which electrical component measures current flow?

The correct answer is Ampere because it is the unit that quantifies the flow of electric current. In the context of electrical systems, the ampere measures how many electrons are passing a specific point in a circuit per second. Essentially, it provides a direct indication of the strength or intensity of the electrical current.

When discussing the other terms: a volt measures electric potential, an ohm measures resistance within a circuit, and a watt measures electrical power, which is the product of voltage and current. Understanding these distinctions is crucial for grasping the concepts related to electrical flow and circuit behavior. In summary, the ampere is specifically tailored to measure the flow of current, making it the most appropriate choice in this context.
