Simulation of some circuits may require the presence of the small series resistance. Equivalent series resistance (ESR) is sometimes specified on manufacturer datasheets. If not, you can define this resistance for a linear capacitor via the dissipation factor (DF), which is also shown on many datasheets.
These subcircuits model a capacitor's self-resonant and series resistive behavior. More complex models can be created that mimic other non-ideal behaviors such as dielectric absorption, leakage and temperature effects. Some capacitor manufacturers provide SPICE models that include these effects.
For polar capacitors, you can define the working voltage range in such a way that the block provides a warning, or an error, if the polarity of the applied voltage becomes incorrect. When an operating limit is exceeded, the block can either generate a warning or stop the simulation with an error. For more information, see Operating Limits.

For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.
You can always use a capacitor with a higher voltage rating, but not always one with a lower voltage rating, as the capacitors breaks down from excessive voltage.
