II. Understanding Capacitors
A. Basic Principles of Capacitors
1. **Definition and Function**: 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 voltage is applied, an electric field forms between the plates, allowing the capacitor to store energy.
2. **Key Parameters**: The performance of a capacitor is defined by several key parameters:
- **Capacitance**: Measured in farads (F), capacitance indicates the amount of charge a capacitor can store per volt.
- **Voltage Rating**: This is the maximum voltage a capacitor can handle before it risks breakdown.
- **Equivalent Series Resistance (ESR)**: This parameter represents the resistance to the flow of current within the capacitor, affecting its efficiency and performance.
