Capacitors are passive electronic components that store and release electrical energy in the form of an electric field between two conductive plates separated by an insulating material, called a dielectric. They are widely used in electrical circuits for various purposes. The main property of a capacitor is its capacitance, measured in farads (F), which determines its ability to store electric charge. Capacitors can store energy temporarily and release it quickly, making them useful in smoothing out voltage fluctuations, filtering signals, and providing timing in electronic circuits. They are also employed in applications such as motor starting, power factor correction, and energy storage in devices like flash cameras and energy-harvesting systems. Understanding capacitors is crucial in electronics and electrical engineering, as they play a vital role in many circuit designs and applications.
