OverviewEnergy storagePulsed power and weaponsPower conditioningPower factor correctionSuppression and couplingMotor startersSensing
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.)
