What Is Voltage
Voltage: An Example of the Concept The concepts of voltage, charge, current, and resistance can be explained with a bucket of water and a hose attached to the bottom. The water represents charge (and the movement of electrons). The flow of water through the hose represents current. The width of the hose represents resistance; a skinny hose would have less flow than a wider hose. The amount of pressure created at the end of the hose by the water represents voltage....
