Capacitors are usually used in applications that require short bursts of energy or fast current flow, and they have lower watt-hour ratings than batteries. Therefore, if you need a device to store a lot of energy over time, then a battery would be the better option. Useful Video: Battery vs Capacitor | Difference between Battery and Capacitor
To understand the difference between the two types of capacitors, let''s dive into them deeply. Decoupling capacitor. Decoupling capacitors are used for Isolating or decoupling two different circuits or a local circuit from an external circuit, in other words the decoupling capacitor is used for decoupling AC signals from DC signals or vice versa.
