Volts can be defined as which of the following?

Volts are defined as a measure of electric potential or the force that drives the flow of electrons through a circuit. This electric potential difference between two points is what causes electric current to flow when there is a conductive path. In a practical sense, when voltage is applied across a resistor, it leads to the movement of electrons, which constitutes an electric current. Therefore, defining volts in terms of a force causing electron flow through resistance captures the fundamental role of voltage in electrical systems.

In contrast, other choices focus on concepts that, while related to electricity, do not accurately define voltage. For instance, measuring electric current pertains to the flow of electrons themselves and is expressed in amperes, whereas electric charge refers to the property of particles that causes them to experience electrical force. Electrical energy, on the other hand, pertains to the work done when electric current flows, typically measured in joules, and is not a direct definition of voltage. Thus, the definition that characterizes volts as a force driving electron flow accurately reflects their essential role in electrical circuits.
