Capacitors function by accumulating electrical charge when a voltage is applied, creating an electric field that enables energy storage. The amount of energy a capacitor can hold is defined by its capacitance value, which is measured in Farads. As the switch closes, the circuit reaches a steady-state where the current flows consistently.
Low Energy Density: Compared to other forms of energy storage like batteries, capacitors store less energy per unit of volume or mass, making them less suitable for long-duration energy storage. High Self-Discharge: Capacitors tend to lose their stored energy relatively quickly when not in use, known as self-discharge.
