Capacitors | Brilliant Math & Science Wiki
Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors.

Low voltage (from about 3.5V to 5.5V) super-capacitors are capable of storing large amounts of charge due to their high capacitance values as the energy stored in a capacitor is equal to 1/2(C x V 2). Low voltage super-capacitors are commonly used in portable hand held devices to replace large, expensive and heavy lithium type batteries as they ...
Balance Resistors for Series Capacitors
The choice to use 500v capacitors rather than 450v gave a safety factor of two immediately (since the nominal voltage was 400V per capacitor, calculating for 450V and using 500V doubled the voltage headroom), which was further increased by lowering the balance resistors in value about 35% so as to draw an even one watt each.

If two capacitors of capacitance C 1 and C 2 are connected in parallel to an input voltage V, then the potential difference across the two capacitors will be the same and equal to V. If Q is the total amount of charge flow (see above) then Q = Q 1 + Q 2 where Q 1 is stored in the first capacitor and Q 2 is stored in the second capacitor.
6.1.2: Capacitance and Capacitors
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
