What is amperage measured in?

Amperage, which refers to the flow of electric current, is measured using an ammeter. This instrument is specifically designed to measure the amount of current in a circuit, quantified in amperes (A). The ammeter is connected in series with the circuit so that the current flows through it, allowing for an accurate reading of the current flowing within that particular section of the circuit.

In contrast, the other instruments have different functions. For example, a voltage meter measures electric potential difference or voltage, while an ohm meter is used to measure resistance in a circuit. A watts meter measures electrical power, which is a function of both voltage and current. Each of these devices serves a unique purpose, highlighting the importance of using the correct tool for measuring different aspects of electrical systems.
