Wireless Charging Essay

Wireless Charging.

Electricity is very important for us these days. We use it in various areas and for all every day uses. We use it to light our rooms, make food, in our cars, computers, phones and etc.. Let us take phones for example.

We use phones every day and they use electricity from batteries. When battery is low on power you need to charge it. We use USB cables to charge them, but there is a way to charge your phone without any cables. Charging without cables is called Wireless charging. Wireless charging uses a Pad which is plugged in to the USB, and simply to charge your phone you need to put it on the Pad.

It works very simple: newer smartphones have very thin coil on the back of phone cover and the Pad has a bigger coil in it with special circuitry that takes electricity from USB which is plugged in the power outlet. Pad coil makes electromagnetic field that produces wireless energy as we call it and as soon as the phone is placed on the Pad, back cover of phone with the coil takes that energy and charges phone.

In conclusion, wireless charger is much better than USB cables because it won’t get tangled up. I think everything that we use will be charged with Wireless charging in future.
