Both capacitors and batteries store electrical energy, but they do so in fundamentally different ways: Capacitors store energy in an electric field and release energy very quickly. They are useful in applications requiring rapid charge and discharge cycles. Batteries store energy chemically and release it more slowly.
A capacitor can store electric energy when it is connected to its charging circuit and when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used as a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed.
In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
When a voltage is applied to a capacitor, the electric charge accumulates on the plates. One plate of the capacitor collects a positive charge while the other collects a negative charge, creating an electrostatic field between them. This electrostatic field is the medium through which the capacitor stores energy.
Remember to always use caution when working with capacitors, as they can store a significant amount of electrical charge even after being disconnected from a power source. Capacitors are versatile electronic components that are used in a wide range of applications across various industries.
For longevity and nonlinear effects at high stresses, it is recommended to keep ample margin on these ratings, especially on the voltage rating. For 230VAC applications, even though typical you wouldn't expect more than about 325V peak over your lines, choose at least a 400V or better even a 450V capacitor.

A capacitor can store electric energy when it is connected to its charging circuit and when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used as a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
