I think you are confusing Amp Hour with Amp. Amp Hour is a metric used in storage for how many amps (flow) can be drawn from a battery bank over a course of time before discharged. Amp by it self is current (flow in the common analogy)
On google:
Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.
