Application of Capacitors
Energy storage: Capacitors are used to store electrical energy in electronic circuits. They can be used to smooth out voltage fluctuations in power supply circuits, and in combination with other components, can be used to filter unwanted noise or interference from a signal.
Applications of capacitors
Capacitors used in RF or sustained high-current applications can overheat, especially in the center of the capacitor rolls. Capacitors used within high-energy capacitor banks can violently explode when a short in one capacitor causes sudden dumping of energy stored in the rest of the bank into the failing unit.
