What is the electrical term for the force that causes electron flow?

The correct answer pertains to the concept of voltage, which is defined as the electrical potential difference between two points in a circuit. Essentially, voltage is what drives the movement of electrons through a conductor, creating an electric current. Think of voltage as the "push" that motivates electrons to flow from one point to another, enabling the operation of electronic devices and systems.

When voltage is present, it creates an electric field that influences the behavior of charge carriers (electrons). The greater the voltage, the more significant the force driving the electrons, leading to a higher current in the circuit, assuming resistance remains constant according to Ohm's law. This relationship highlights the fundamental role voltage plays in electrical engineering and circuits—without voltage, there would be no current flow.

The other terms relate to different aspects of electrical systems. Ampere-hours are a measure of electric charge, capacitance refers to a component's ability to store electrical energy in an electric field, and inductance relates to the ability of a component to store energy in a magnetic field due to current flow. While essential in their right, these concepts do not directly describe the force responsible for electron movement.
