True or False: The greater the difference in electron concentration between the two points, the higher the battery voltage?

The statement that the greater the difference in electron concentration between two points results in higher battery voltage is true. Voltage can be understood as the potential difference between two points in an electrical circuit, which is driven by the separation of charge. When there is a significant difference in electron concentration—essentially a difference in electric potential—this creates a stronger drive for electrons to move from the area of higher concentration to the area of lower concentration.

In a battery, this potential difference is crucial because it enables the flow of current when the circuit is completed. A larger difference in electron concentration translates into a greater push for charge movement, which corresponds to a higher voltage reading across the battery terminals. This relationship is fundamental to the operation of batteries and other electrochemical cells, making the assertion accurate based on the principles of electrodynamics and electrochemistry.

Other options, while they touch on various aspects of electrical design and conditions, do not encapsulate this direct and fundamental relationship between electron concentration difference and voltage generation as clearly as the correct answer does.
