SUMMARY
The change in voltage between two capacitor plates is defined as V=ED, where E represents the electric field strength and D denotes the displacement between the plates. This relationship contrasts with the equation V=-ED, which describes the potential change in the direction of the electric field. The confusion arises from differing definitions of voltage, where some refer to it as electric potential while others define it as potential drop. According to Ohm's Law, the current I through a resistor causes a voltage drop V=IR, which is distinct from the behavior observed in capacitors.
