This device allowed for the storage of electrical charge and laid the groundwork for future developments in capacitor technology. Over the years, advancements in materials and manufacturing processes have led to the creation of various types of capacitors, each with unique characteristics and applications. The evolution of capacitors has been closely tied to the growth of electrical engineering and technology, enabling innovations in consumer electronics, industrial machinery, and renewable energy systems. III. Basic Principles of Capacitors A. Definition of Capacitance Capacitance is defined as the ability of a capacitor to store electrical charge. It is measured in Farads (F), a unit named after the British scientist Michael Faraday. The capacitance of a capacitor depends on several factors: 1. **Surface Area**: The larger the surface area of the capacitor plates, the greater the capacitance. 2. **Distance**: The closer the plates are to each other, the higher the capacitance. 3. **Dielectric Material**: The type of insulating material placed between the plates affects the capacitor's ability to store charge. B. How Capacitors Store Energy Capacitors store energy in the form of an electric field created between their plates when a voltage is applied. During the charging process, electrons accumulate on one plate, creating a negative charge, while the other plate loses electrons, resulting in a positive charge. This separation of charge creates an electric field, which stores energy. When the capacitor discharges, the stored energy is released back into the circuit, providing power to connected components.
