What is the term for the potential difference caused by an unequal number of electrons between two objects?

The term for the potential difference caused by an unequal number of electrons between two objects is referred to as voltage. Voltage represents the driving force that pushes electric charges through a circuit, and it is the measure of electric potential energy per unit charge. When there is an imbalance in the number of electrons, it creates a difference in electric potential between the two objects, leading to voltage. This concept is fundamental in understanding how electricity works, as it is voltage that prompts current to flow in a circuit when a conductive path is available.

Current, on the other hand, is the flow of electric charge, which occurs due to this potential difference (voltage). Resistance refers to the opposition that a material presents to the flow of electric current, while power indicates the rate at which electrical energy is consumed or converted to other forms of energy. Each of these terms plays a crucial role in electrical circuits, but in this context, voltage clearly describes the potential difference due to an electron imbalance.
