Which term best defines the flow of electric charge?

The term that best defines the flow of electric charge is current. Current is a measure of the flow of electric charge through a conductor, such as a wire, and is typically expressed in amperes (A). This flow occurs when there is a difference in electric potential, or voltage, across the conductor, allowing charged particles (usually electrons) to move.

To understand the concept further, it's important to note the relationship between current and other electrical terms. Voltage refers to the electric potential difference that drives the charge flow. Resistance, on the other hand, is a property of a material that opposes the flow of current. Power represents the rate at which electrical energy is transferred or converted and is calculated by multiplying current by voltage.

By defining current specifically as the flow of electric charge, it clarifies its fundamental role in electric circuits and systems. This provides a clearer understanding for anyone studying foundational electrical concepts.
