Energy Stored on a Capacitor
This energy is stored in the electric field. A capacitor. =. = x 10^ F. which is charged to voltage V= V. will have charge Q = x10^ C. and will have stored energy E = x10^ J. From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV.
A review on the recent advances in hybrid supercapacitors
Presently, supercapacitors have gained an important space in energy storage modules due to their extraordinarily high power density, although they lag behind the energy density of batteries and fuel cells.

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).
