When moving parallel capacitor plates without opening the switch, the voltage remains constant while charge and electric field strength are not constant. Conversely, if the plates are moved after opening the switch, both charge and electric field strength remain constant. The work done in moving the plates affects the energy dynamics, transferring energy back to the power supply when the switch is closed. The dielectric constant remains unchanged unless the dielectric material itself is altered. This discussion highlights the differences in electrical properties based on the timing of the switch's operation relative to the movement of the plates.
