Capacitor

You can think of a capacitor as a battery with very low capacity.

You can charge and discharge it just like a battery.

The capacitor is often used to introduce a time-delay in a circuit.

For example to blink a light.

It’s commonly used for removing noise, or making the supply voltage of a circuit more stable.

There are many capacitor types. Most commonly, we divide them into polarized and non-polarized capacitors.
