What is the electrical term for the electromotive force (EMF) that causes electron flow?

The term that describes the electromotive force (EMF) responsible for causing electron flow is voltage. Voltage is essentially the potential difference between two points in an electrical circuit, which drives the flow of electric current when a circuit is completed.

When there is a voltage applied across a circuit, it provides the necessary push for electrons to move from the negative terminal to the positive terminal, establishing a flow of current. In essence, without voltage, there would be no incentive for electrical charges to move, and thus no current flow would occur.

Ampere-hours is a unit of electric charge, often used to measure the capacity of batteries. It quantifies how much current can flow over a certain period but does not represent the driving force behind that flow.

Capacitance refers to the ability of a component or circuit to store an electric charge and is a measure of a capacitor's ability to hold onto electrical energy.

Inductance is associated with the ability of an inductor to store energy in a magnetic field when electric current flows through it. It is related to how a magnetic field collapses when the current is switched off, influencing the current flow in circuits but does not serve as the source of electron movement.

Therefore, voltage stands out as the correct
