What is the unit of measurement for the rate of current flow?

The unit of measurement for the rate of current flow is the Ampere. This unit quantifies the amount of electric charge that passes through a conductor in a specified amount of time. Specifically, one ampere is defined as one coulomb of charge moving past a point in a circuit in one second. The concept of current flow is fundamental in understanding electrical circuits, as it represents the flow of electrons and is crucial for determining how electrical devices operate.

Voltage, or volts, measures the electric potential difference between two points and is not a measure of current itself. Watts represent power, which is the rate at which electrical energy is consumed or generated, and it is derived from the product of voltage and current (P = V × I). Ohms measure resistance, which is the opposition to current flow in an electrical circuit. Thus, while all these units are related to electricity, the Ampere specifically denotes the flow of current.
