Energy stored (E) in terms of charge (Q) and capacitance (C): E = ½ × Q² / C. Energy stored (E) in terms of charge (Q) and voltage (V): E = ½ × Q × V. To use the calculator, users input the capacitance and voltage values, or the charge and capacitance values, depending on the available information. The calculator then computes the energy ...

It should be pointed out that R d representing the dielectric losses also can be placed in parallel the capacitor. However, R d placed in series can be directly used to reflect the energy loss and to be a part of the ESR. If the capacitor discharge is oscillatory, the dielectric loss resistance (R d) can be achieved by the use of the dissipation factor DF …

This is the case of energy storage application. The effects of pulses having high peak current, but short duration (20-40 /spl mu/s), are compared to the effects of pulses having lower peak current, but higher duration (200-300 /spl mu/s). The comparison is made between pulses having the same I/sup 2/t.

The usable energy in the single string of eight (in series) is W = 1*[(10F/8)/2*((2.7V*8)2-6V2)] = 269.1J Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs.
