II. Basic Concepts of Capacitance A. Definition of Capacitance Capacitance is defined as the ability of a capacitor to store charge per unit voltage. It quantifies how much electric charge a capacitor can hold for a given voltage across its plates. The higher the capacitance, the more charge the capacitor can store. B. Units of Capacitance (Farads) The unit of capacitance is the farad (F), named after the English scientist Michael Faraday. One farad is defined as the capacitance of a capacitor that stores one coulomb of charge at a potential difference of one volt. In practice, capacitors are often measured in microfarads (µF), nanofarads (nF), or picofarads (pF), as farads represent a large amount of capacitance. C. Factors Affecting Capacitance Several factors influence the capacitance of a capacitor: 1. **Surface Area of Plates**: The larger the surface area of the conductive plates, the greater the capacitance. This is because a larger area can hold more charge. 2. **Distance Between Plates**: Capacitance is inversely proportional to the distance between the plates. As the distance increases, the capacitance decreases because the electric field strength diminishes. 3. **Dielectric Material**: The type of dielectric material used between the plates affects capacitance.
