*The [[energy]] stored in a [[capacitor]] is half the [[energy]] required to [[Capacitor Charge|charge the capacitor]]. Since The energy required to [[Capacitor Charge|charge]] the [[capacitor]] is the [[Electrical Work|work done]] to by the [[Electrical ChargeBattery|charge]] the [[capacitorbattery]] which 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]] since 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 with the [[Electrical Charge|charge]] stored in the [[capacitor]] changesthen the [[energy]] stored by a [[capacitor]] is half the product of the [[Electrical Charge|charge]] and [[Potential Difference|potential difference]]. This provides a *The maximum [[Energy Efficiency|efficiency]] of 50% to a [[capacitor]]s is 50% which is far less than the [[Energy Efficiency|efficiency]] of a [[Electrical Battery|battery]].
