The equivalent capacitance of capacitors in parallel is calculated by simply adding the capacitances of all individual capacitors together. This principle stems from the fact that when capacitors are connected in parallel, they all share the same voltage across their terminals. As a result, the total charge stored by the combination increases, effectively leading to a larger capacitance.

In practical terms, if you have multiple capacitors connected in parallel, the total capacitance increases because each additional capacitor adds its individual capacitance value to the total. This is contrary to how series connections work, where two capacitors reduce the overall capacitance due to the increased total distance across which charge must be stored.

Understanding this concept is critical, especially in applications such as power supplies and filtering, where modifying capacitance can have a significant impact on the circuit behavior. The insights gained from this principle also help in predicting how changing the arrangement of capacitors can affect their capacity to store energy.
