Capacitors are passive electronic components that store and release electrical energy in a circuit. They 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. Capacitors are widely used in various applications, including filtering, timing, and energy storage.
As technology advances, the variety of capacitor models and their applications continue to grow. Proper training on these models is essential for engineers, technicians, and anyone involved in electronics. Understanding the different types of capacitors, their specifications, and their applications can significantly impact the performance and safety of electronic devices.
