An electrical condenser is commonly known as a capacitor, with its primary function being to store and discharge electrical energy. However, there are several other terms that can be used to describe this device, such as an electrostatic device, energy storage device, or dielectric. These synonyms are based on the fundamental principles of how a capacitor operates by using two conductive plates separated by a non-conductive material, ensuring that the energy stored within it is kept in a stable state. With the advancements in technology, capacitors have become an essential component in modern electronics, enabling them to operate more efficiently.
