Practical Considerations
A capacitor of any given size may be relatively high in capacitance and low in working voltage, vice versa, or some compromise between the two extremes. Take the following two photographs for example: This is a fairly large capacitor in physical size, but it has quite a low capacitance value: only 2 µF.

CHV is a high voltage capacitor (rated at 400 V) that typically accounts for around 20% of the total capacitance. CLV is a low voltage capacitor (160 V) that accounts for about 80% of the total capacitance. This split in capacitance enables the capacitor volume to be reduced by up to 50%, leading to an overall reduction in adaptor size of up …

Get PriceCommon Generator Parts To Fix "No Or Low Voltage"
Capacitor. The capacitor has two functions; it induces voltage into the rotor as well as regulates voltage. A bad capacity will result in a low voltage reading from the generator as the power being generated will be from the residual magnetism of the rotor (usually about 2-5V). To test a capacitor, a multi-meter that can test capacitance is ...

Get PriceCapacitor Specifications: what they mean
The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75).
