The difference is that a battery uses electrochemical processes to store energy, while a capacitor simply stores charge. As such, capacitors are able to release the stored energy at a much higher rate than batteries, since chemical processes need more time to take place. . Capacitors are devices which store electrical energy in the form of electrical chargeaccumulated on their plates. When a capacitor is connected to a power source, it accumulates energy. . There are many applications which use capacitors as energy sources. They are used in audio equipment, uninterruptible power supplies, camera. . Capacitors, as well as other capacitors used for other purposes in circuits, can store charge long after they have been disconnected from the. . A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary, or like other types of . Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
