The Series resistance and Parallel conductance parameters represent small parasitic effects. The parallel conductance directly across the capacitor can be used to model dielectric losses, or equivalently leakage current per volt. The current is positive if it flows from positive to negative, and the voltage across the capacitor is equal to
the nominal current of the charger in a straight line. The nominal power of a standard charger can only be utilised at its nominal voltage. The extended operating area (EOA) of the HPS series allows the capacitor to be charged with its rated power from a much lower voltage compared to the nominal voltage. This reduces the capacitor''s charging time.

When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage
The voltage across a capacitor cannot change instantaneously because an infinite current would be required. So if you connect the two capacitors together with ideal wires then at that instant the two capacitors will still have their original, different voltages.
