A capacitor is a device designed to store electrical energy. The process of charging a capacitor entails transferring electric charges from one plate to another. The work done during this charging process is stored as electrical potential energy within the capacitor.
Capacitors are essential elements in electrical and electronic circuits, crucial for energy storage and management. When a voltage is applied across a capacitor, it accumulates electrical energy in the electric field formed between its plates.
The process of charging a capacitor entails transferring electric charges from one plate to another. The work done during this charging process is stored as electrical potential energy within the capacitor.
