What is the definition of electricity in terms of electron movement?

The definition of electricity as a potential that results in the movement of electrons in a conductor correctly captures the fundamental nature of electrical current. Electricity refers to the flow of electric charge, which is primarily carried by electrons in conductive materials like metals. When there is a potential difference (voltage) across a conductor, it creates an electric field that exerts a force on the electrons, causing them to move. This movement of electrons is what constitutes an electric current.

In contrast, the other options highlight different aspects of electricity or related concepts but do not define electricity in terms of electron movement. The notion of a force pushing electrons through a vacuum refers more specifically to phenomena associated with vacuum tubes or cathode rays. Describing electricity as a type of energy stored in batteries focuses on one of its applications rather than its intrinsic nature. Lastly, linking electricity to magnetic fields relates to electromagnetic theory but does not adequately define the core concept of electricity itself, which is fundamentally about the movement and flow of electrons.
