1. **Series Configuration**: In a series configuration, capacitors are connected end-to-end. The total capacitance decreases, and the voltage rating increases. This configuration is less common for capacitor banks used in power systems.
2. **Parallel Configuration**: In a parallel configuration, capacitors are connected alongside each other. The total capacitance increases while the voltage rating remains the same. This is the most common configuration for capacitor banks, as it allows for greater energy storage and reactive power support.
B. Advantages and Disadvantages of Each Configuration
Series Configuration:
- *Advantages*: Higher voltage rating, useful for specific applications.
- *Disadvantages*: Reduced total capacitance, not ideal for power factor correction.
Parallel Configuration:

II. Basic Concepts of Capacitors
A. Definition of a Capacitor
A capacitor is a passive 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.
B. How Capacitors Work
