Amperage is the rate at which electric charges flow through a conductor. In a circuit, current measures how much charge passes a point each second, so it corresponds to the flow of charges—typically electrons in a metal wire. This flow is measured in amperes, with 1 ampere equaling 1 coulomb per second. The other terms describe different things: energy per unit charge is voltage (potential energy per charge), resistance is the opposition to current (ohms), and potential difference is the driving force that pushes charges (voltage). So amperage best matches the flow rate of charges.
