Current is the term used to describe electrical charges moving through a wire. Sort of like the currents and eddies in a creek. We want to measure the flow of electrical charges over time. It is similar to measures like a gallon, i.e., a big aggregation of water molecules. One coulumb per second is defined to be one ampere .
Amps are the unit of velocity of electrical flow.
Think of a water tower, with water stored in a tank at the top. The higher the tower, the stronger the water pressure at the bottom of the tower. It is measured in Watts. Think of a water wheel. The amount of water flowing over the wheel is the current.
