WIRELESS ELECTRICITY

“WIRELESS  ELECTRICITY’’

 

 

 

ABSTRACT

Wireless electricity  is the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load without interconnecting wires.

Cell phones, game controllers, laptop computers, mobile robots, even electric vehicles capable of re-charging themselves without ever being plugged in. Flat screen TV’s and digital picture frames that hang on the wall—without requiring a wire and plug for power. Industrial systems and medical devices can be made more reliable by eliminating trouble prone wiring and replaceable batteries. The technique exploits simple physics and can be used to charge a range of electronic devices over many metres.The system could replace the miles of expensive power cables and billions of disposablebatteries.

There is something like 40 billion disposable batteries built every year for power that, is used within a few inches or feet of where there is very inexpensive power.Trillions of dollars,had also been invested building an infrastructure of wires "to get power from where it is created to where it is used."

The working of wireless electricity involves"One coil is the source, the other is the device. The source generates a magnetic field which induces a current in the device. This is converted into the power the device wants to use."

If this technology is adopted in future it will make everyday products more convenient, reliable, and environmentally friendly.
