Electric Current

Real World Example

Imagine trying to fill a swimming pool with water using a garden hose. The way the water flows steadily through the hose to fill the pool is similar to how electric current flows through a wire. Just as the water represents the volume and flow rate needed to fill the pool, the electric current represents the flow of electric charge measured in amperes (A), which fills up the "energy demand" of a circuit. In this analogy, the water represents the electric charge, the hose is the wire, and the flow rate of water equates to the amperes that measure how much charge is moving through the circuit at any given time.
