The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a "vacuum capacitor." However, the space is usually filled with an insulating material …
5.12: Force Between the Plates of a Plane Parallel Plate Capacitor
We connect a battery across the plates, so the plates will attract each other. The upper plate will move down, but only so far, because the electrical attraction between the plates is countered …
18.4: Capacitors and Dielectrics
An electric field is created between the plates of the capacitor as charge builds on each plate. Therefore, the net field created by the capacitor will be partially decreased, as will the potential difference across it, by the …
