What unit measures the push that is given to electrons?

The correct choice measures the electrical potential difference or voltage that drives the flow of electrons in a circuit. This push is essential for electrons to move through conductors and is a fundamental aspect of electrical circuits.

When a potential difference is present, it causes electrons to move from areas of higher potential to areas of lower potential, creating an electric current. Thus, volts are the units that quantify this essential “push” behind electric charge movement.

Understanding this concept is critical for grasping topics related to electricity and circuitry, where the relationship between voltage, current, and resistance is foundational to electrical engineering and physics.
