What is the primary purpose of series connected capacitors?

The primary purpose of series-connected capacitors is related to enhancing voltage levels. When capacitors are connected in series, their total capacitance decreases, but the voltage rating increases. This means that the combined voltage they can handle is greater than that of a single capacitor alone. As a result, series-connected capacitors are often used to ensure that higher voltage levels can be managed within a circuit, providing stability and reliability.

In contrast, while capacitors do store energy, efficiency in energy storage is not the main goal of connecting them in series. While series capacitors can mitigate voltage fluctuations, the main benefit lies in their ability to handle increased voltage levels rather than directly reducing voltage flicker. Additionally, series-connected capacitors do not inherently increase current flow; rather, they affect the overall impedance of the circuit. Thus, the enhancement of voltage levels is the most relevant outcome when employing series connections of capacitors.
