What is the device called that is specifically designed to measure amperage?

• A. Ammeter
• B. Voltmeter
• C. Ohmmeter
• D. Capacitor

Answer: (A)

An ammeter is the device specifically designed to measure amperage, which is the flow of electric current in a circuit. It is connected in series with the circuit so that all the current flowing through the circuit also passes through the ammeter. This allows it to accurately measure the amount of current in amperes (A).

In contrast, other devices listed serve different functions. A voltmeter measures voltage (the electric potential difference) across two points in a circuit and is typically connected in parallel with the components being measured. An ohmmeter is used to measure the resistance of a component, displaying its resistance in ohms (Ω). A capacitor, on the other hand, is a passive electrical component that stores electric energy temporarily in an electric field, but it does not measure any electrical quantities. Understanding these distinctions helps clarify why the ammeter is the appropriate choice for measuring amperage.
