Electrical potential refers to the amount of electric potential energy per unit charge at a specific point in an electric field. It indicates how much work would be needed to move a positive test charge from a reference point, usually at infinity, to that point without any acceleration. The unit of electrical potential is the volt.
In simpler terms, electrical potential can be thought of as the "pressure" that pushes electric charges through a circuit. Higher electrical potential means a stronger push, which can lead to more current flow when connected in a circuit. This concept is crucial for understanding how batteries and power sources operate.
