Frequently asked questions

Why does series wiring reduce capacitance?
Each capacitor in series adds to the effective gap between plates, reducing the ability to store charge. It is the mirror image of parallel resistors.
When would I wire capacitors in series?
To increase the voltage rating of a capacitor bank, or to achieve a smaller capacitance than any available single component.
