Which of the following best describes the relationship between voltage and electron flow?

The relationship between voltage and electron flow is rooted in Ohm's law, which states that the current (or flow of electrons) is directly proportional to voltage when resistance is held constant. This means that as the voltage applied across a circuit increases, the potential difference drives more electrons to flow through the conductor, resulting in an increase in current.

In this context, when voltage increases, it enhances the electrical energy driving the electrons, thereby increasing their flow. This relationship is fundamental in understanding how electrical circuits operate, especially in the design of electronic devices where controlling the flow of electrons is crucial for functionality.

Therefore, the correct answer accurately reflects this principle that higher voltage leads to greater electron flow, assuming other factors like resistance are constant.
