II. Basic Concepts of Capacitors
A. What is a Capacitor?
A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric field is created, allowing the capacitor to store energy in the form of an electric charge.

where \( C_1, C_2, C_3, \) and \( C_n \) are the capacitances of the individual capacitors.
2. Explanation of the Formula
This formula indicates that when capacitors are connected in parallel, the total capacitance increases. This is because each capacitor can store additional charge at the same voltage, effectively increasing the overall capacity of the circuit to store energy.
