→About Capacitor Energy
*[[Energy]] stored in a [[capacitor]] can be used in various applications like powering the lights designed to flash and providing [[energy]] for defibrillators.
*[[Capacitor]]s store energy in the [[Electric Field|electric field]] between their plates.
*The stored [[energy]] is released when the [[capacitor]] is [[Capacitor Discharge|discharged]].
*[[Capacitor]]s can deliver [[energy]] quickly compared to [[Electrical Battery|batteries]].
*Used in [[Power Supply|power supplies]] to smooth out fluctuations in [[Potential Difference|voltage]].
*The [[energy]] stored in a [[capacitor]] is half the [[energy]] required to charge the capacitor. Since the [[Electrical Work|work done]] to [[Electrical Charge|charge ]] the [[capacitor ]] is given by the product of the [[Electrical Charge|charge]] supplied by the [[Electrical Battery|battery ]] and the [[Potential Difference|potential difference]] of the [[Electrical Battery|battery]] provides a constant flow of [[Electrical Charge|charge]] and constant [[Potential Difference|potential difference]]. However, as the [[Potential Difference|potential difference]] across the [[capacitor]] changes as the [[Electrical Charge|charge]] stored in the [[capacitor]] changes. This provides a maximum efficiency of 50% to [[capacitor]]s which is far less than the efficiency of a [[Electrical Battery|battery]].
