In electrical terms, what does "current" measure?

Current, in electrical terms, measures the flow of electric charge, which is primarily the movement of electrons through a conductor. This flow is quantified in amperes (A) and represents the rate at which electric charge is passing a point in the circuit. Understanding this concept is pivotal in grasping how electrical systems operate, as current is one of the fundamental elements in ohm's law, which relates current, voltage, and resistance.

The other options refer to different electrical concepts. Voltage flow refers to the electric potential difference that drives the current but does not measure the current itself. Resistance is a measure of how much a material opposes the flow of current, while power consumption relates to the rate at which electrical energy is converted into another form of energy, such as heat or light, and is calculated using current and voltage but does not define what current itself measures.
