Applications of Parallel Capacitors. By combining several capacitors in parallel, the resultant circuit will be able to store more energy as the equivalent capacitance is the sum of individual capacitances of all capacitors involved.
Customer ServiceWhen a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.

Customer Service(a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.
Parallel Combination increases the total capacitance in a circuit, which helps filter noise, stabilize power supplies, and enhance energy storage capacity. A combination of capacitors refers to how multiple capacitors are connected within an electric circuit. Capacitors can be arranged in different configurations.
when connected in parallel, the two capacitors and its equivalent capacitance could be modeled as all having the same separation between their plates, but the equivalent capacitance has twice the area of its equivalent-plate compared to the area of the plate of one of the original capacitors.
The expression in Equation 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q / C between its plates.
Series Combination, Capacitors are connected end-to-end so that the same current flows through each Capacitor. In a parallel combination, capacitors are connected across each other's terminals, so they share the same voltage. Capacitors can be combined in more complex configurations involving series and parallel connections.
