What are smart capacitors used for
Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

Can 2 capacitors be used as one?
You do decrease the resistance of the capacitor, but resistance is not a significant aspect of the design. The leakage resistance is supposed to be as low as possible. When two capacitors run parallel, the plate area increases, and thus, the total capacitance increases to the sum of all capacitances.
