The unit of measurement for current flow is _________ and is measured with a _________.

The unit of measurement for current flow is the ampere, commonly abbreviated as "amp." This unit quantifies the amount of electric charge that flows past a specific point in an electrical circuit per second. In order to measure this flow of current accurately, an ammeter is used, which is specifically designed to display the current flowing through a circuit.

Understanding these units and instruments is crucial for anyone working with electricity, as they provide the essential measurements needed to ensure safe and effective operation of electrical systems. An ammeter is typically connected in series with the circuit, enabling it to measure the flow of current directly, while other devices mentioned in the options are suited for measuring different electrical parameters: ohms for resistance, volts for voltage, and watts for power.
