What must a power source maintain to enable effective electrical flow?

To enable effective electrical flow, a power source must maintain a potential difference between two points. This potential difference, often referred to as voltage, is essential for creating the conditions necessary for electrical current to flow through a circuit.

When a power source generates a potential difference, it essentially provides the energy required to push electrons through conductors. This movement of electrons constitutes an electric current. If there is no potential difference, there is no driving force to move the electrons, and consequently, no electrical flow will occur.

Maintaining a potential difference is crucial in various applications, whether it be in household circuits, power distribution systems, or electronic devices, as it directly affects the functionality and efficiency of the entire electrical system.
