What does the ampere measure?

• A. The pressure of electricity
• B. The current or flow of electricity
• C. The resistance in an electrical circuit
• D. The energy consumed over time

Answer: (B)

The ampere, often referred to as "amp," specifically measures the current or flow of electricity in a circuit. It quantifies the amount of electric charge passing a point in a conductor per unit time. In essence, one ampere corresponds to one coulomb of electrical charge flowing through a point in a circuit in one second. This understanding is fundamental in both electrical engineering and practical applications, as it helps in determining how much energy can be delivered to devices and systems within an electrical framework. Understanding the flow of current is crucial for ensuring that circuits are appropriately designed and function efficiently, making the ampere a foundational unit in the study of electricity and electronics.
