Essentially, a capacitor is like a small battery, producing a potential difference (i.e., a voltage) between the two plates, separated by the insulating divider called the dielectric (which can be many materials, but is often ceramic, glass, wax paper or mica), which prevents current from flowing from one plate to the other, thereby maintaining the …
batteries
In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage will also become 9V. This will happen because there is no resistance between the capacitor and the battery, so the variation of current by time will be infinite.

Electric field in a parallel plate capacitor
A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material).A dielectric material is a material that does not allow current to flow …
Can we use a capacitor with battery to fast charge it?
No, if you pump enough energy into those caps to charge the battery, it will destroy the battery when put into series. Apply 100V to a 12V battery and see what happens. And even if it did work, you would need MASSIVE MASSIVE caps since capacitors have much ...
