What defines the flow of current in terms of charge and time?

The correct answer, which defines the flow of current in terms of charge and time, is based on the equation I = Q/T. In this formula, I represents the electric current, Q denotes the quantity of electric charge that flows, and T indicates the time during which the charge flows. Thus, the equation states that the current is equal to the charge divided by the time, effectively quantifying how much charge passes through a conductor per unit of time. This fundamental relationship is essential in understanding electrical circuits and the behavior of electric charge.

In contrast, the other options represent different concepts and relationships in electrical theory. The equation I = Q/V refers to the relationship between current, charge, and voltage, which is not a direct definition of flow over time. I = T/Q does not align with the conventional definition of current, as it incorrectly places time as the numerator. Lastly, I = V*R describes Ohm's Law, which defines the relationship between current, voltage, and resistance, rather than current in relation to charge and time. Each of these variations highlights important electrical concepts, but only the first correctly captures the definition of current flow in terms of charge per time interval.
