Two oppositely charged parallel plates are a fixed distance apart. Which phrase best describes the relationship between the electric field intensity (E) between the plates and the potential difference (V) across the plates?

the electric field is proportional to the voltage divided by the separation of the plates,

Explanation:

This parallel plate configuration is widely used, as it creates a uniform electric field between the plates. Where the potential and field differences are related by

              DV = E d

That is, the electric field is proportional to the voltage divided by the separation of the plates, in general all these configurations are called capacitors
