Amperage is the flow rate (or current) of electrons through the circuit. The circuit measures its current in amps (short for amperes). Amperage is therefore the measurement of the amount of electricity flowing through a wire or device. An amperage rating tells the greatest amount of current a wire, device, or appliance can carry.

More specifically, amperage is a term used to describe the number of electrons moving past a fixed point in a circuit in one second. This current is measured in units called amps/amperes.

The term amperage may be understood better through the analogy of hydraulic (liquid) systems. Amperage is like the water volume pumped through your system. The more electricity you need for a component, the fatter the wire you will need to feed it.
