How is voltage like a staircase?

Voltage can be likened to a staircase because it represents a difference in electrical potential, much like the height difference between steps. Just as you need to ascend or descend steps to change levels, electrical current flows from higher voltage to lower voltage. Each step corresponds to a specific voltage level, and the greater the height difference, the more potential energy is available for the current to do work. In this way, voltage sets the stage for how electricity moves through a circuit.
