Capacitive Power Supply: Circuit Design and Calculations
Table showing the X rated capacitor types and the output voltage and current without load. ... If the supply voltage is 18V, the voltage that is to be dropped across R to get 12V output is 6volts. If the maximum Zener current allowed is 100 mA, then R will pass the maximum desired output current plus 5 mA . So the value of R appears as:

Capacitor in 12VDC motor circuit
To me this explains why the fan slowly shuts down - the capacitor charges and then becomes an open spot in the circuit. To make this stranger, two of these fans exhibit this behavior and a third one does not. They are all wired the same (though the capacitor on the one that works appears to be of a larger rating). Maybe that capacitor …
DIY Battery Spot Welder! : 8 Steps (with Pictures)

18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
How to Charge a Capacitor: A Comprehensive Guide for …
In a parallel configuration, capacitors are connected side by side, creating multiple paths for current flow. When charging capacitors in parallel, each capacitor receives the same voltage from the power source, but the current is divided among them based on their individual capacitance values.

How Capacitors Work
The voltage rating is the maximum voltage a capacitor can handle. So if you have a circuit where the voltage across the capacitor can reach 12V, you need a capacitor with a voltage rating of 12V or more. It is recommended to use a capacitor rated for more than 12V so that you have some safety margin. The capacitance value is given …
