Capacitors, energy storage and energy release

Click For Summary
SUMMARY

Capacitors are essential components in electrical circuits, capable of storing and rapidly releasing energy. The energy release occurs when a capacitor is connected to a load, such as a small resistance or an inductor, which facilitates the quick discharge of stored energy. Dielectric breakdown is detrimental and should be avoided in practical applications. Capacitors are commonly utilized in circuits for applications like oscillators, flashlights, and power supply smoothing to mitigate 50/60Hz ripple.

Just a short concept question for understanding...

I understand that a capacitor stores a charge,

However I'm told that capacitors can be used to store up a charge and release it very quickly.
How does this energy get released is what I don't understand.

To my understanding of a capacitor it stores a charge and if it gets too much charge there's a dielectric breakdown.

How is this useful in a circuit?

Thank you.

Dielectric breakdown is not useful in a circuit as far as I know. The way to quickly release the energy is to connect a small resistance to it. You could connect an inductor to get a large magnetic field, or make an oscillator, use it for a flashlight, or use it in a power supply to smooth out the 50/60Hz ripple.
