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 by the tension in the spring. Calculate the equilibrium separation (x) between the plates as a function of the applied voltage (V). (Horrid word!
There are many different styles of capacitor construction, each one suited for particular ratings and purposes. For very small capacitors, two circular plates sandwiching an insulating material will suffice.

There are differences in notation methods among countries such as Japan (JIS), the United States (EIA), and Europe (EU, IEC). The larger the area of the capacitor''s electrode plates and the closer the distance between the two electrode plates, the higher is its ability to store electricity.
$begingroup$ What you are learning about is an ideal capacitor, made from a material with zero electrical resistance. Of course such a thing doesn''t exist, but if the resistance is small, it is a pretty good approximation.

A double-layer capacitor consists of two electrodes, which are spatially separated by a liquid or solid electrolyte, but still electrically connected to each other. By applying a voltage, a so-called Helmholtz double layer is formed on each of the two electrodes. This means that a very thin layer of anions of the electrolyte is formed at the anode.
