SUMMARY
The change in electric potential between two capacitor plates is accurately represented by the equation V = -ED, where E is the electric field and D is the displacement. This relationship holds true as the electric field points from the positive to the negative plate, indicating a decrease in potential when moving in the direction of the field. The dot product of the vectors ensures that the sign of the potential change is correctly accounted for, confirming that moving along the electric field results in a negative change in potential.
