Why the cylinder like shape is placed at the end of your charger ?

Nowadays  technology is used and followed by every single person in the world, we are all surrounded

With it & without smartphone life is impossible it has became the part of our body.

 So today I am going to show u that Why cylinder module part is placed at the end of your charger ??

So most of the devices are working with an AC current (alternating current) with very high frequencies,which leads to disturb the signal of other devices such as televisions, wifi, bluetooth, routers, radios etc.

These cylinder modules  are used to prevent the frequencies from disturbing other devices

There is a magnetic material which has the property of absorbing these unwanted frequencies.

And the ferrite core, this cylinder minimizes energy losses, further optimizing the flow of current that runs inside the cable.
