6 FAQs about [Parallel capacitor voltage protection]

Do all capacitors in a parallel connection have the same voltage?

All capacitors in the parallel connection have the same voltage across them, meaning that: where V 1 to V n represent the voltage across each respective capacitor. This voltage is equal to the voltage applied to the parallel connection of capacitors through the input wires.

How does a parallel capacitor work?

In a parallel configuration, the positive terminals of all capacitors are connected together, and the negative terminals are also connected together. This effectively increases the plate area of the equivalent capacitor, resulting in a higher total capacitance. Example:
