How Capacitors Work | HowStuffWorks

Inside the battery, chemical reactions produce electrons on one terminal and the other terminal absorbs them when you create a circuit. A capacitor is much simpler than a battery, as it can''t produce new electrons — it only stores them. A capacitor is so-called because it has the "capacity" to store energy.

Lead-free Nb-based dielectric film capacitors for energy storage …

U T indicates the total energy density, which has a unit of J·cm −3. Q max, V, d, and A are the free charges in the electrode, the applied voltage, the distance between parallel plates of the capacitors, and the area of the electrode, respectively. E and D represent the applied electric field strength and electrical displacement, respectively, in the dielectric layer.

Capacitors

When capacitors are placed in parallel with one another the total capacitance is simply the sum of all capacitances. This is analogous to the way resistors add when in series. So, for example, if you had three capacitors of values 10µF, 1µF, and 0.1µF in parallel, the total capacitance would be 11.1µF (10+1+0.1).
