Capacitors are fundamental electronic components that store and release electrical energy. They consist 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. Capacitors play a crucial role in modern technology, enabling the functionality of countless devices and systems. This article explores the various types of capacitors, their key application areas, emerging trends, challenges, and the future of capacitors in technology.
Capacitors come in various types, each designed for specific applications based on their characteristics:
