Capacitors are fundamental components in electrical and electronic systems, playing a crucial role in a wide array of applications. Defined as passive electronic devices that store and release electrical energy, capacitors are essential for managing voltage and current in circuits. Their importance in modern technology cannot be overstated, as they are integral to the functionality of everything from consumer electronics to industrial machinery. This blog post will explore the various application scenarios of capacitors and the industries that rely on them, providing a comprehensive overview of their significance in today's world.
Capacitors consist of two conductive plates separated by an insulating material known as a dielectric. When voltage is applied across the plates, an electric field is created, allowing the capacitor to store energy. The amount of energy a capacitor can store is determined by its capacitance, which is measured in farads (F).
