Ever wondered what’s the use of this small cylinder in your laptop charger?
So, most of us have been using laptop for years. And, most of the time, it is plugged in to an electricity socket. But we missed to notice something odd about that charger of your laptop.
Ever wonder what that is for? Geeks would bet their life, it is important as hell. For one tiny piece of information, it is known as Ferrite Bead or ferrite choke.
This helps to isolates the laptop from the electro-magnetic noise that occurs from the waves picked up by the cable, or from the noise in AC-DC converter. It dissipates high-frequency currents in a ferrite ceramic, and helps make the most powerful noise suppression device! It is called a core, block, or EMI ring. So, that is what it is all about.
Do share this significant piece of knowledge with your friends.
