Capacitors: Components for Storing and Releasing Electrical Energy

Capacitors differ from batteries in that they store energy in an electric field rather than through chemical reactions, enabling them to charge and discharge at much faster rates. However, capacitors generally have lower energy density and higher self-discharge rates than batteries, limiting their ability to store charge over extended periods.
