100 uf capacitor voltage rating

The voltage doesn't affect the capacitance in any way.

Well, for ceramic capacitors voltage does matter. Ceramics (excluding C0G/NPO) have a voltage (and temp) coefficient associated with them. The closer the applied voltage is to the rated voltage, the less effective capacitance you get. For cheap dielectrics like Y5V and Z5U the loss can be as high as 60%.

Yes, but we're not talking ceramics here - we're talking electrolytics.
